The Post has a photo gallery of photos from the bike polo court on Capitol Hill (one block from my house).
(After I wrote the above I found the article that goes with it)
Bicycle polo takes the traditional sport and swaps the horses and preppy associations for battle-scarred bikes and hockey's rough-and-tumble mentality. Helmets and pads are optional; trash-talking is encouraged. Premack had a camera with him, so he started shooting, trying to stay out of their way. "It can get pretty intense. One guy must have gone down five or six times," he says. The teams are coed, and everyone on the court is fair game. "No one was saying, 'Go easy on her, she's a girl,' " Premack says.
