There's a HRSFA tradition of public games of Capture the Flag. There's nothing quite like running madly around public or semi-public spaces battling over a scrap of cloth . . . so someone's decided to bring public Capture the Flag to Brooklyn. Evidently there's going to be a Manhattan game soon, too. Nothing's off-limits, which is the best part - you can run through stores, hide in buildings, whatever. (Just don't get arrested.) It sounds like fun.
