Cyclists from the Naval Research Laboratory (NRL) and other cyclists who use the bike path between the Anacostia Naval Air Station and the South Capitol Street Bridge cleaned up the path on Saturday, May 8. More than a dozen cyclists worked for over 4 hours cleaning the path in memory of David van Keuren. David was the historian at NRL and an avid bicyclist who rode this path on his daily commute to NRL. David was killed by a hit-and-run motorist on South Capitol Street March 26 as he was cycling to work.
