Looks like the eastern part of the neighborhood is getting a historic walking trail as well -- Columbia Heights had one finished earlier this year. The Georgia Ave/Pleasant Plains trail will start at 6th and T and head up to the Georgia Ave-Petworth Metro station, about 1.5 miles total -- here's a map.
On Tuesday at 6:30 there's a meeting on the trail, with representatives from Cultural Tourism DC, the Emergence Community Arts Collective and more. The trail is funded by the DDOT and the US Highway Administration. The meeting is at the ECAC building, 733 Euclid Street NW.
The trail will include signs on the Martin Luther King Jr riots, Howard University, Griffith Stadium, the old Washington Senators baseball stadium, the area's Caribbean heritage, Abraham Lincoln, and more. Sounds pretty interesting.
