Critical Mass is this Friday, the 31st, and is always on the last Friday of the month. Meet at Justin Herman Plaza on the San Francisco Embarcadero at 6p.
Is Critical Mass a protest or a celebration? I've never know. What do you think?
CM has its own special vogue. Sometimes people wear funny outfits. Sometimes people come right from work.
Sometimes people are just plain gorgeous.
Everyone is always expressing their own unique style.
And everyone comes to have fun!
