Another sign spring is coming: This past Friday, the police arrestd 37 Critical Mass bikers. The city has been demanding permits for the more-bikes-less-cars advocacy groups to gather and ride through the city during their last Friday of the month rides. The city's argument is that the mass ride causes traffic issues, and permits would be necessary at Union Square (where the ride starts) and other city streets. Plus, participants would not be able to publicize the ride! This is totally Gooliani-era tactics! So far, the city's attempts to permitize the rides have failed when Times Up, the organization that organizes the rides, has filed lawsuits and judges have ruled with them.

Critical Mass's 12th birthday will be celebrated on the April 29 ride. Gothamist suggests people stands on the sidewalks and hand out cupcakes to riders! Plus Gothamist on Critical Mass.
