* NATS TICKETS/PROMOTIONS AT THE BALLPARK: Single game tickets for the Nats' 2015 season go on sale to the general public Thursday, Feb. 19, at 10 am. (Season ticket holders get their shot on Wednesday.) Believe it or not, this will be the Nationals' 11th season in DC (and the 8th at Nats Park), so there are a whole slew of anniversary-related promotions planned this year, including 10-Year Tuesdays, six games that will feature special guests, pregame ceremonies, and giveaways. Other offerings of note include the Great Moments in Nationals History Bobbleheads, the Jayson Werth Chia Pet, and the Anthony Rendon Garden Gnome, plus six Pups in the Park days and a Star Wars day.

* FAT TUESDAY AT CANAL PARK (SORT OF): The Capitol Riverfront BID will be celebrating Mardi Gras on Tuesday, Feb. 17, with a "Second Line" march scheduled for noon in Canal Park, featuring local band Brass Connection. There will also be king cake served in the light cube, and of course beads will be flung. (Checking to find out whether they will be marching through the snow. UPDATE: No parade, no band, no cake, but beads are still to be flung.)

* VAN NESS FUNDRAISER AT NANDO'S (MAYBE): Tuesday, Feb. 17 is also the Van Ness Elementary fundraiser at Nando's Peri-Peri. From 6 pm to 10 pm, the restaurant will donate 40 percent of its receipts from all sales made to people with the fundraiser flyer in hand. (And if you didn't RSVP, that's okay.) UPDATE: If there's a heavy coating of snow, this may get pushed to March. The call will be made on Tuesday morning. UPDATE II: It's been snowed out--the new date is March 24.

* JOB FAIR AT ARENA STAGE: Newly minted councilmembers Charles Allen and Elissa Silverman are co-sponsoring the latest edition of the DC Job Fair, at Arena Stage, on Friday, Feb. 20, from 10 am to 2 pm. Businesses that will be there looking to hire include Giant Food, Clark Construction at the Wharf, CSX, DC Water, Sears, Big Bus Tours, the Architect of the Capitol, and others. There will also be a number of organizations represented that provide support services for those looking to re-enter the job market.

* LIVE MUSIC AT BLUEJACKET: Because they aren't packing enough people in on Friday nights, the brewery at 4th and Tingey is launching a live music offering on alternate Fridays up until the start of baseball season. It starts on Feb. 20 at 10 pm with Crystal Youth. No cover charge.

* LASER CAT AT THE YARDS: If you're near 3rd and Tingey this weekend and are wondering about the lasers, music, and cries of "Pew! Pew!" emanating from the old Building 170, it's Laser Cat, being presented by the Washington Project for the Arts. The free tickets appear to be gone for the Friday/Saturday night sessions (oops), but you can still RSVP to Laser Cat Kids on Saturday, Feb. 21 from noon to 2 pm. There will be cat-ear making, balloon and glitter tattoo artists, the inevitable face painting, and of course, a huge freaking feline.

* SECURITY EXERCISES: From Feb. 2 to Feb. 13, naval bases and installations in the DC area will be conducting an annual security training and readiness exercise, dubbed SOLID CURTAIN-CITADEL SHIELD 2015. "Measures have been taken to minimize disruptions to normal base operations, but there may be times when the exercise causes increased traffic around bases or delays in base access. Area residents may also see increased security activity associated with the exercise."

* BLOOD DRIVE: There is a community blood drive on Saturday, Feb. 7, from 10 am to 4 pm. The truck will be parked outside of Lot 38 Espresso at 2nd and L streets, SE, and Lot 38 is offering a free drink for each donor. Reservations encouraged but not required. Read more here about Davon and Kai, the young residents whose need for blood products inspired the event.

* NO MORE LOT P: A season ticket holder was informed by the Nationals that Lot P--the garage below 1015 Half Street--has been dropped from the lineup of parking lots available to season ticket holders. With CBS Radio and the National Labor Relations Board preparing to move into the building (and with Bonchon in preparations to open in the ground floor), it's perhaps not a surprise that there may not be quite so many spaces available in the building anymore. But at least a a surface lot should reappear at 1st and N (the old Spooky Building 213 site) in the coming months after being out-of-circulation last year.

The pre- and post-game festivities two blocks east of the ballpark have expanded somewhat since the initial announcement a few days ago. This is all free, open to both ticket holders and schlubs, and is the work of the Capitol Riverfront BID:

Saturday, Oct. 4:

The Natitude outside the ballpark had already started ramping up over the past few weeks, as evidenced here, but no doubt there will be much more to come before Friday's opening game of the National League Division Series.

After my jaw came up off the floor, I raced down to get this batch of "before" photos of the ballpark's footprint and immediate surroundings. A lot of my all-time favorite shots are in this lineup, including the one at left, of Half and M.

While there were plenty of plans for the neighborhood already in the pipeline, the jolt that this provided changed the trajectory of the area's redevelopment from a somewhat leisurely pace to a rocket blasting off. And it certainly changed my life.

See the rest here.

* UNLEASHED BY PETCO: It was rumored back in May, and there's still been no official announcement from Forest City, but a building permit issued last week seems to be the final confirmation that Unleashed by Petco is coming to the Boilermaker Shops.

* CSX: The Post reports that "It could be a few weeks before the Federal Highway Administration releases a decision on the proposed expansion of the Virginia Avenue Tunnel in Southeast Washington." The "Record of Decision" hasn't yet been finalized. In the meantime, the Committee of 100 has let it be known that any decision short of an indefinite delay will result in a lawsuit. (Shocker!)

* HALF STREET: WBJ talks to new Half Street poobah Jair Lynch about his group's plans for the Half Street hole, now that they've bought it from Monument Realty. "While the project is expected to remain a mix of residential, retail and hotel, Lynch said he is now considering condos in addition to apartments, tweaking unit sizes, adding green features and amenities and bringing in a 'completely different retail mix.'" (Longtime area observers note that in Monument's original plans, the two residential buildings at the south end of the block were planned to be condos and apartments. And of course it's easy to "change" the retail mix when there isn't any to begin with.) They hope to get underway by 2016, WBJ says.

* MLB LATE NIGHT WITH METRO: WTOP: "Although the Washington Nationals have clinched the NL East, the team has not reached a deal with Metro to keep trains running past midnight during home playoff games." The Metro policy is that the Nationals would have to pay at $29,500 deposit to stay open an extra hour during the week; some of you may remember that back in 2012, the Nats did not step forward to pay, so Livingsocial offered to foot the bill.

The Fairgrounds will be open on both days, even if you aren't going to the concerts and you're just desperate to drink beer and play corn hole in a public setting.

If you want free music, on Friday there's the Yards Park concert series of course, with Jah Works providing the entertainment this week.

In other events news, readers have reported recent activity around the *other* little red building in the neighborhood, the one behind USDOT on the northwest corner of 3rd and Tingey, with what appeared to be automotive representatives on hand most of Wednesday. I'm not sure what is brewing, but a building permit was issued earlier this month for "ONE DAY SPECIAL EVENT FOR BMW SHOW." Anyone have the scoop? (UPDATE: Sounds like a private event.)

* KILL THE WABBIT: Don't forget that Opera in the Outfield returns tomorrow (Saturday, May 3), with a simulcast of Mozart's "The Magic Flute." The show is at 7 pm, but the gates open at 5 pm for the variety of "pre-game" activities, including a coloring station, a meet and greet with M&M's Miss Brown (!) and the living statue of Babe Ruth (!!), and more.

* HEY THERE, DELILAH: The NatsLive lineup for this summer has been announced. Mark your calendars for the Plain White T’s on June 5, Austin Mahone on July 19, and Martina McBride on August 16. The concerts are free for anyone who has a ticket to that day's game.

* TAKE ME TO THE RIVER: The Ballpark Boathouse at Diamond Teague Park opens for its second season tomorrow (Saturday, May 3). Kayaks and canoes will be available for rental, if you want to explore the shores of the neighborhood from the other side.

* BUY ME SOME PEANUTS: The Nationals really want you to come to see the team play the Dodgers next week. The Tuesday, May 6 game is "Federal Workforce Day," plus the first 25,000 fans will receive an MLB Network eco-friendly shopping bag. Then on Wednesday, May 7, it's Weather Day, at which the Fox5 weather team "will conduct an interactive presentation to educate local students on the various types of weather conditions in the region and how they affect a Nationals baseball game." It's a 1:05 game, but the weather-related festivities begin at 9:45 am. There's also discounted tickets; see the Nats Weather Day page for details.

* THIS WEEK IN CSX: In case you haven't heard, a new date has been set for the DC council's hearing on a proposed resolution to tell the House Committee on Transportation and Infrastructure to have a hearing about the Virginia Avenue Tunnel. It's now set for April 30 at 10 am (moved from March 25), and the announcement explains how you can be heard at this hearing, should you choose to be heard.

Other than that, I got nuthin. Unless you know someone who grew up in northeastern Wyoming many years ago and might be in this batch of uncaptioned photos handed down through my family. (Great-aunt Lucy was a teacher out there, so there's lots of pictures of kids in front of small rural schoolhouses.)

UPDATE: To flesh these tidbits out a bit, I'll add this just-posted WaPo piece on when the Nats should sell naming rights to the ballpark.

The prices are what were being charged today, though for some of the lots it might be that lower prices will be charged for games with smaller crowds. So use the prices on the map as a guide, not 100 percent gospel.

Since the 2013 season pretty much went down the rabbit hole for me, I can't say for certain what's truly new and changed among the offerings, but here at least is What's New to Me:

* There is a $10 lot in the McDonald's parking lot at South Capitol and I, SE.

* The surface lots on the former Monument Realty properties at South Capitol and N and Half and M are back, charging $30.

* The little parking lot that popped up on South Capitol south of N next to the Camden apartment building was charging $30 this weekend, but it sounds like their rates will be pretty fluid depending on demand.

* We already knew that the lot at the NGA building would disappear this year (as the building itself will be), but it should return next year.

* It looks like Lot W hasn't been cut in half yet by the start of construction at the Lofts at Capitol Quarter, but be prepared for that to happen.

There's also the story of Nats Lot F at 1st and M, which a few weeks ago had disappeared from the team web site's parking inventory. But it is now back, albeit shrunken to a footprint that looks remarkably similar in size to the one that the Skanska 99 M office building will be built on as part of the sizeable Ballpark Square mixed-use development.

Small traffic cones separate this new Lot F from a now-unofficial lot immediately to the south, and a birdie told me that this is because the owner of that lot--which looks remarkably similar in size to the mid-block portion of Ballpark Square being developed by Grosvenor--is planning to start construction there Any Minute Now, so that lot is expected to be closed within the next few months.

Whether this is actually the case, and whether it means both the planned 325ish-unit apartment building and the 170ish-room hotel will both get underway, or just one or the other, I guess we'll have to see. No announcement yet as to an operator for this hotel, which is different from the Hampton Inn now under construction at the south end of the block.

The new signs for 99 M say "fall 2016," so that would track with this smaller Lot F being able to remain in inventory through the end of this season.
