At Wednesday night’s Capital Bikeshare open house, the folks at the bike transit system gave cycling-related prizes to attendees who came closest to correctly answering obscure Capital Bikeshare trivia questions. Here at The Washington Post, we have no tangible prizes to give, but in very, very specific party settings, here are some Bikeshare facts you can dish to impress your friends.
