Two upcoming events from the Anacostia Waterfront Corporation that might be of interest: On Earth Day, April 21, the AWC is running an Anacostia River Earth Day Cleanup and Celebration, with Canal Park being of the four cleanup sites (along with the Southwest Waterfront, Marvin Gaye Park, and Kenilworth Parkand Poplar Point). See their announcement for details, and also check out the Anacostia Watershed Society's Earth Day cleanup plans for the Anacostia. The next day, April 22, as part of Cultural Tourism DC's Walkingtown Tours, the AWC is sponsoring four different routes, none of which are actually in Near Southeast but which still might be of interest (the eastern riverfront and Poplar Point, Kingman and Heritage Islands, Hill East, and Marvin Gaye Park). The announcement has times and locations and whatnot.
