Brooklyn Critical Mass

Meet at Plaza St West and Prospect Park West, Prospect Heights, Brooklyn. Subway: 2, 3 to Grand Army Plaza. If you harbor fantasies of clean air and car-free streets, hop on your fixed-gear or ten-speed and cruise for a cause with members of the bike-group-cum-political-organization Critical Mass. The monthly ride, which has been happening since 2004, finishes at the Brooklyn side of the Williamsburg bridge. Just don’t forget to bring your safety lights, bell and helmet.
