* ENVIRONMENTAL FORUM: On March 21, there is to be a forum with DC mayoral candidates focusing on sustainability and environmental issues, at the Boilermaker Shops at 300 Tingey St., SE, from 6 to 8 pm. It has been organized by the local chapter of the Sierra Club along with the Capitol Riverfront BID, the neighborhood group Near Southeast Community Partners and a coalition of multiple groups now operating under an umbrella group called United for a Healthy Anacostia River. Former mayor Anthony Williams will be on hand, and the organizers says that the candidates who will appear include Carlos Allen, Jack Evans, Mayor Gray, Vincent Orange, and Tommy Wells.

* AT THE DRIVE-IN: Presumably in anticipation of their not-as-yet-underway Ballpark Square office/residential/hotel/retail project, developers Grosvenor, McCaffery and Skanska are co-sponsoring with the BID a "Groundbreaking at the Capitol Riverfront Drive-In Movie Weekend" on Friday, March 21 and Saturday, March 22. They are inviting folks to "pull into the converted drive-in movie theater at 1st and M Streets, SE to watch great films and purchase popular DC food truck cuisine." Friday's movie will be Toy Story, and Saturday's will be The Matrix. Both screenings start at 7:30 pm.

For future reference:

There will be food trucks, prizes, cold drinks, music, and opportunities to get educated on how city agencies, organizations, and business and working to "make this the most sustainable, living city in the country."

Tickets are on sale now, and benefit Living Classrooms of the National Capital Area.
