The video explains quite a bit. We're looking for folks to join our team "The Audballs" there is a promotion code "teamup" that reduces the registration fee to only $25 (normally $75). This year the ride will begin and end at RFK stadium along the Anacostia, final ride not determined yet.
Glad to answer any questions. Also posted in the SE region.
