Times-up! of New York promotes critical mass on their website. Here's an illegal, but creative way of promoting critical mass on the williamsburg bridge.



Just come to a consensus on a time and a place and let it happen. Traditionally it happens on the last friday of every month, though Brooklyn Critical Mass happens on the 2nd friday of every month, is police escorted and strangely civil compared to the Manhattan CM (we didn't have to stop traffic to run red lights, a fleet of scooter cops did it for us). Good luck, and where are you located?
