So you say you want to start a revolution? Then steer clear of the East Bay Bike Party. Unlike Critical Mass, for which it's sometimes mistaken by onlookers, this group ride through the streets of the East Bay every second Friday is strictly politics-free. It isn't designed to make any statements, break any rules, or polarize participants. In fact, organizers exhort riders repeatedly to follow traffic laws, stick to the right-hand lane, and be respectful of pedestrians and motorists — even when East Bay Bike Party's hundreds of bicyclists easily outnumber everyone else on the road. Routes vary from month to month but tend to be mostly flat and about ten miles long. Keeping with the good-times vibes, each ride is themed (e.g., Pajama Party, Where's Waldo, Zombie Homecoming) and concludes with a party hosted by a local business or venue. Activism has its place, but here joy prevails.
