(Though this is in reference to the neighborhood "around"
Nationals Park, the locations are actually in Southwest. But it's still worth posting.)
From the Nationals: "The Washington Nationals Dream Foundation will team up with Earth Conservation Corps to give area residents and local businesses the opportunity to help beautify the neighborhood surrounding Nationals Park. More than 100 volunteers will take to the streets from 8am to noon [on Friday, July 30] to clean up areas at three separate locations - the Matthew Henson Center (2000 Half Street, SW); the intersection between 1st and Q Streets, SW; and the park at 3rd and I Streets, SW. Nationals Pitchers Tyler Clippard and Craig Stammen will also join volunteers for a portion of the morning's clean-up." I understand that Colin Balester is going to be part of the cleanup as well; I don't know if that's in addition to Clippard and Stammen, or in place of one of them.
