* South on South Capitol: The Fairgrounds folks are launching a "South on South Capitol" southern rock concert series, featuring local and regional country and southern rock bands, along with mechanical bull rides (!), food trucks, and the Bullpen bar. The first one is scheduled for May 25, then June 22, July 27, and Aug. 24. (They're all Fridays.) Admission is free.

And, speaking of Fairgrounds, there's a corrected list of dates for their Sunday Family Days, which are just once a month (next one on June 3).

* Science + You: If you've wandered by the southeast corner of the Foundry Lofts building just north of the Yards Park, you may have already seen the Science + You exhibit. It's geared toward kids ages 3-8, giving them the hands-on chance to "become scientists for a day." It's being managed by Living Classrooms of the National Capital Region, and was developed by Kohl Children's Museum in Chicago in cooperation with scientists from Abbott. The web site has lots of photos of the various interactive stations within the exhibit. It runs until Aug. 5, and is open from 12:30-4 pm Tuesday-Friday and 10 am-4 pm Saturday and Sunday. Admission is free.

* Ladies Night: The Nats' first Ladies Night of the 2012 season is Thursday (May 17), and they're going with a "Pretty in Pink" theme along with a Majestic women's apparel fashion show, drink specials, games, prizes, music, and whatnot. VIP tickets are $40 and include access to the party tent at 1st and Potomac from 5 to 7 pm along with special group seating. If you can't make the tent happy hour, you can buy a $25 ticket and enjoy the Scoreboard Pavilion festivities. (The tickets include a $10 concession credit.)

* Bike to Work: Friday, May 18 is Bike to Work Day, and the Yards Park is one of the pit stops, from 7 to 9 am. Alas, the free t-shirts for the first 11,000 registrants have already been snapped up, but you probably already own a t-shirt or two anyway.

* Battle of the Beltways: Be forewarned that the right-near-first-place (!) Orioles are coming to Nats Park for a Friday-Sunday interleague series, and so all three games will probably bring a lot of fans and traffic.

* Third Eye Blind: I mentioned last week about the Wallflowers being lined up for the 2nd of the NatsLive free post-game concerts, and soon after the word went out that Third Eye Blind would be playing the third concert, on Aug. 18 after the Nats play the New York Mets. Dierks Bentley kicks off the series on June 2, and tickets for all three games are on sale. (The concerts are free for game-ticket holders.)

And of course Friday also brings the Yards Park Friday Concert Series, with Justin Trawick performing this week. And, as a heads up, next Thursday (May 24), the Front Flicks Outdoor Movie Series gets underway, with Lara Croft: Tomb Raider.

* Friday brings the first Truckeroo food truck festival of 2012, from 11 am to 11 pm at the Fairgrounds at Half and M SE. Its Facebook page today listed the truck lineup as including BBQ Bus, Big Cheese, Cajunators, Cap Mac, Chef Driven, Curbside Cupcakes, DC Empanadas, DC Slides, Doug the Food Dude, Hot People, Hula Girl, Tapas, Pleasant Pops, Red Hook Lobster Pound, Sinplicity, Sweetz Cheesecake, and Takorean.

* If you want to walk off some calories, you can also head to the Yards Park for the Friday Evening Concert, from 6:30 to 8:30 pm. US Navy Band The Cruisers will be the music act this week, and food will be by Red Apron Butchery, Buzz Bakery, and Luke's Lobster, with beverages by ChurchKey.

* Saturday brings the finale of the Kennedy Center's Street Arts Across America festival with Street Arts in the Park, a day-long event at the Yards Park, from noon to 6 pm. The full lineup of music and events is available on the official web site.

* On Sunday, the Fairgrounds will be celebrating Mother's Day with its first Family Day, from 11 am to 4 pm, with "carnival games and prizes, inflatable and mechanical rides, children's entertainers and live musicians," plus food trucks.

Admission for all of these events is free. And the forecast looks pretty sweet.

And then the neighbors who live in that big building on South Capitol Street will be returning to town on Monday, for a series against the Padres that includes a 1:05 pm game on Tuesday (which is also Weather Day!), and then a weekend series against the Orioles, which should make for big crowds.

New this year is that the lineup of musical acts is going to be selected by OnTap Magazine, and that food will be provided by Red Apron Butchery, Buzz Bakery, and ChurchKey. (Buzz Bakery is one of the tenants slated to come to the Boilermaker Shops, and of course ChurchKey is the sibling of Boilermaker's Bluejacket brewery.)

The food options are described thusly by the press release: "Red Apron, a small-batch producer of locally-made and handcrafted charcuterie from Chef Nate Anda, will serve a variety of artisan hot dogs with housemade condiments. Buzz Bakery, a bakery and coffee shop led by award-winning Pastry Chef Tiffany MacIsaac, will offer seasonal treats such as baked goods, ice cream, popsicles and fresh juices. Greg Engert, who manages the beverage programs at Birch & Barley, ChurchKey, Rustico and other area restaurants, will oversee a weekly rotating selection of hand-selected craft draft beers and wines." There will also be a rotating lineup of second food vendors each week, such as familiar food trucks Stix, BBQ Bus, Luke's Lobster, Dutch Mill Catering and Doug the Food Dude.

The music will be a "wide range" of styles, including jazz, Top 40, country, salsa, and reggae.

* Joel Osteen Ministries' "America's Night of Hope" is coming to Nationals Park on Saturday--here's the Washington Post's story on Osteen and the plans for the event. Doors open at 5:30 pm and the festivities start at 7 pm, if you're wanting to plan your evening around the crowds. If you're coming to the neighborhood for it, my Visiting Nats Park page can help you find your way.

* Want to know how the Nats Park field is cared for, and who takes care of it? The Post profiles head groundskeeper John Turnour and his work.

* A reader tells WashCycle about being stopped from biking on the Navy Yard portion of the Riverwalk. That promenade has always been signed as prohibiting bicycling, but with increased publicity for using the Riverwalk as a biking trail (including Tuesday's ribbon cutting of the new bridge across the CSX tracks), the issue of bicycles along the Navy Yard/Yards Park/Teague stretch is going to keep bubbling up, perhaps even moreso when the new 11th Street Local bridge opens soon with its wide pedestrian/cycling paths making the connection between both sides of the river even easier.

* Speaking of that new 11th Street Local bridge, much streetscape work has been done recently on O Street (new pavement, curbs, and brick paver crosswalks), and it looks like the concrete should be poured before too long to complete the connection from O to where the bridge begins to rise above the river. Maybe I'll actually get over there with my camera soon.

* Speaking of streetscapes, there's a new sidewalk on L Street between 1st and New Jersey, to go with the new sidewalk on Half between I and K.

* The Capitol Riverfront BID would love it if you'd fill out either their residential survey (if you live in the neighborhood) or the employee survey if you work here.

* Jonathan O'Connell at WaPo looks at how developer Opus East hit the skids, right as it was trying to finish 1015 Half Street. (Opus was also the developer behind 100 M, but it was completed before everything truly fell apart.)

* The Mayor is having a Ward 6 Fiscal Year 2013 Budget Town Hall Meeting tonight (April 25) at 6:30 pm at Eastern High School, 1700 East Capitol Street.

* The next meeting of Police Service Area 106 is on Saturday, April 28, at 10 am at the Capper Seniors building at 900 5th St., SE.

What else is going on?

UPDATE: Adding a link to Washington City Paper's profile of "The Nautical Yards", a "site-specific dance and theater piece inspired by the Washington Navy Yard" being performed at the Yards Park Thursday through Saturday (April 26-29) at 7 pm. Premium seating is $30, general admission is free.

And I should probably remind that tickets for Springsteen at Nats Park on Sept. 14 go on sale Friday (April 27) at 10 am.

* I assume everyone's heard by now that Bruce Springsteen will be playing at Nats Park on Sept. 14. Tickets go on sale on Friday, April 27 at 10 am at tickets.com. (If I'm not showing appropriate enthusiasm, I apologize, but Springsteen just hasn't ever really done it for me. I think I was permanently scarred by everyone around me going so crazy for him when I was in college, during the whole Born in the USA era. I just hid in my room and listened to R.E.M., and U2, and the Smiths, and Squeeze, and Elvis Costello, and....)

* The Nats' current homestand continues for the rest of the week, with tonight being the first $2 Ticket Tuesday of the season. Then there's Neighborhood Night on Thursday, April 19, followed by the season's first Pups in the Park game at 1:05 pm Saturday, April 21, and Kids Opening Day at 1:35 pm Sunday, April 22.

* If you're not availing yourself of tonight's $2 Ticket Tuesday, perhaps you might want to check out the Capitol Hill Chamber of Commerce's session on real estate development in and around Capitol Hill, which will be focusing on the areas east of South Capitol and south of East Capitol, which includes Near Southeast. Tommy Wells is scheduled to be part of the lineup. It's from 7 to 9 pm at the Meader Theater (NCC's new home) at 535 8th St., SE.

* Saturday, April 21 is Lantern Making Family Day at the Yards Park, as part of the lineup of events as the Cherry Blossom Festival comes to a close. There are two sessions, at 10 am and noon, followed by a parade/procession through the park.

* It's a bit outside my boundaries, but residents and others may be interested to know that the new Anacostia Riverwalk Trail Bridge crossing the railroad tracks just north of Pennsylvania Avenue will be opening on April 24.

And, some non-event tidbits:

* Square 696, the block bounded by I, K, Half, and First owned by DRI and Jamestown and originally branded as "The Plaza on K," is apparently being relaunched as "Congressional Square," though that doesn't seem to have filtered down to any web sites just yet. It's still an 825,000-square-foot office and retail project.

* On Opening Day, I noticed a lot of cars parked in the fenced-off lot on the southeast corner of 1st and M SE that belongs to the former National Geospatial Intelligence Agency building. I asked Forest City about it, and they said that they will offer parking in that lot for certain games where big crowds are expected, but aren't planning to make it available for daily use.

* In the 700 block of Virginia Avenue, the Miles Glass building and the auto repair shop next door are no more, but at least they are now permanently enshrined as entries #168 and #169 in the Demolished Buildings Gallery. A parking lot is expected to be built for temporary use, while the National Community Church works on its plans for a larger events space on the site.

The framing and Tyvek-ing is underway on 3rd Street south of L, in the shadow of the 300 M Street office building, as Capitol Quarter continues its march toward completion. I also took a lot of photos of other CQ Phase II blocks, so spend some time in the Capitol Quarter Phase 2 Expanded Photo Archive (and scroll down a bit) to hop through the many (many!) before-and-afters.

Then there's the Boilermaker Shops at the Yards, where some work was being done even on Easter Sunday. The walling off the interior space for the different tenants has begun, with the studs visible--and some drywall has even gone in on the mezzanine level, as seen at right, in a view from 4th Street, through what will be the Bluejacket space.

The work is on-going at Canal Park, but continues to not be terribly exciting from a photographic standpoint, unless you're wowed by images of new curbs. But the Canal Park Expanded Photo Archive can take you for a walk around the park's perimeter to see the current views, if you don't see it every day. (I also like my barbed wire shot [above right], the result of desperation after being without photos from the east side of 2nd and L for a very long time now. But, no, I didn't jump the fence.)

I also enjoyed being watched very closely by a USDOT security guard with a clipboard as I took photos of the park's progress from the south side of M Street. "What are you taking photos of?" she finally asked, trying to sound stern. "Stuff," I replied, as I smiled and kept walking.

There's also updated shots from 225 Virginia/200 I (seen at right), with the landscaping now starting to go in.

If you want to see today's entire batch (213 of 'em), here they are, remembering to click the fun little icon if you want to see the entire range of photos for a certain location. If you want even more new-ish pictures, here's photos I took around 1st and Half Streets on Tuesday, to get the Fairgrounds exterior into the official archive.

Now I need to go find that peanut butter bunny. I think I earned it.

First, a few new entries in the What's New Around the Ballpark? lineup:

* On Tap Magazine surveys the neighborhood with "The Hidden Gem That is the Capitol Riverfront." (Another jewelry metaphor to go with the Post's "Diamond in the Rough" piece from Sunday.)

* WJLA wandered around looking at the ballpark environs.

* The Post's Going Out Gurus blog checked out the Fairgrounds' sneak peek on Tuesday. (Though what's the deal with the photos that look like they were taken through a veil? Will this Instagram obsession never ebb?)

* WTOP runs down the options for arriving at the ballpark by water taxi. (American River Taxi, by the way, says that they are almost sold out for the April 12 home opener.)

Some other items:

* Two reports from MLB.com on the Wounded Warrior Amputee charity softball classic, played Tuesday after the Nats-Red Sox exhibition. The Warriors pounded their celebrity challengers 17-4.

* "DC Modern Luxury" magazine's Men's issue picks the Foundry Lofts as one of the city's "Best Bachelor Buildings." Go here, then click on the Best Bachelor Buildings subhed to get to page 62, then look at the bottom of the page. (As an aside, the write-up sounds even better if you imagine it being spoken by Stefon.)

* Or, if you like your tidbits a bit less glossy, Multihousing News has "Foundry Lofts Blazes Trail on DC Riverfront."

* Bluejacket gets a big write-up and cover photo in Beer Advocate magazine, though we don't get to read it online. You'll just have to make do with the Sept. 2011 batch of photos from inside the Boilermaker Shops the brewery has put up on their Facebook page.

* Nineteen "experts" have picked the Nationals to make the playoffs this year. No pressure!

* The 11th Street Recreation Bridge meeting happened while I was out of town, but here's Greater Greater Washington's write-up of it. But, before the meeting, WCP's Alex Baca posted four thoughts about the concept, with some items of concern worth noting (though "it is a cool idea!" is the first bullet point).

* Don't forget that the public meeting about the possible recreational re-use of the old outbound 11th Street Bridge span is on Wednesday, March 28, at 6:30 pm.

* Justin's Cafe has now posted the information on its April 14 block party, both on Facebook and its new JustinsCafeEvents.com web site. It will run from 11 am to 9 pm, offering a line-up of local craft brews (including "beer trucks" from Port City Brewery and DC Brau), and 106.7 The Fan FM will be broadcasting from there. "All ages welcomed, 21 and over to drink." Money is also being raised for free youth baseball and softball programs through the DC Grays and S.M.A.R.T. Camps and Clinics. (The Nats play the Reds at 4:05 pm that day.)

* On April 1 (well, April 2, technically), the Union Station-Navy Yard Circulator bus starts its summer hours, running from 6 am to 9 pm weekdays and 7 am to 9 pm Saturdays, with extended service on Nationals game days.

* The Southwester reports that there's a Neighborhood Night at Nationals Park on Thursday, April 19. "The team will honor the vibrant spirit of the neighborhood by featuring local residents in various pregame activities, including throwing out the first pitch, delivering the lineup card and greeting the players as they take their positions on the field." Near Southeast and Southwest residents can also get discounted tickets to games throughout the season, but I'll make you follow the link to find out about that!

* The Earth Conservations Corps will be leading volunteers in a cleanup of the wetlands at Diamond Teague Park on April 21, from 9 am to noon, as part of the Anacostia Watershed Society's Earth Day events. (They do want volunteers to register/RSVP in order to participate.)

* A bit farther down the pike, the Kennedy Center is presenting "Look Both Ways: Street Arts Across America," a week-long festival showcasing all manner of free performances and events from May 6-12. One of the May 6 kick-off events will be from 11:30 am to 1:30 pm at Nationals Park and the Fairgrounds (old Bullpen) on Half Street, and the closing event on May 12 from noon to 6 pm will be at the Yards Park.

One reader sent me both videos and a series of iPhone photos showing the activity, but it was DCIst that got the money shot: a photo clearly showing a big ole' UXO (oh, heck, let's have fun and call it a bomb). This site is of course part of the old Navy Yard footprint, where all manner of exploding items were manufactured for many years.

Since no one's reported any big BOOMs in the intervening time, the clean-up must have proceeded according to plan. The question is, will there be any more surprises once digging resumes?

UPDATE: Here's WJLA's report on the day's festivities, and then DCist unearthed these two videos of the gun factory from 1952.

UPDATE II: While we're all enjoying being a bit flip about all of this, it is of course a serious business to be doing this excavation with such items laying around. Forest City tells me that the work is being done in accordance with guidelines from the Army's Explosive Ordnance Division, and that indeed over the past several weeks sitework has needed to be stopped temporarily because of the unearthing of "munitions debris." Each time, the police department's bomb squad is called in, who then determine whether the EOD folks from Ft. Belvoir should be called in, as they were today.

Forest City also says that it's anticipated that most buried artifacts and debris are found within the first 10 to 15 feet of soil when excavation, so once they get past that level, they expect the finds will trail off. And, it's not just munitions being found--foundations of several homes that were on site prior to the lot being used by the Navy have been found, as well as a Civil War-era cannon.

But the company does want to emphasize that "public safety and the safety of the site workers are paramount for Forest City, so we will continue to strictly abide by the established practices and involve the qualified technicians whenever and as soon as necessary." This includes having a former Navy munitions expert on site at all times as a "spotter," and using a two-part method when excavating, scooping the dirt from the hole in small quantities and spreading it out to be looked at and cleared before it's then scooped into a truck for removal from the site.

Whether this will impact the timeline for 1212 4th's construction depends on how many stoppages there end up being.
