Another Critical Mass for San Francisco?

According to SFist, the bike people are launching another version of Critical Mass this Friday. It will snarl traffic on the first Friday of the month, joining the regular Critical Mass that snarls traffic on the last Friday of the month. The bike people will now be snarling traffic twice a month instead of once a month. They're calling the new version the San Francisco Bike Party. It starts 8:00 o'clock Friday night at AT&T Park and ends up at the Civic Center.

Like Critical Mass, the Bike Party is organized anonymously, so it has no permit, and no one is responsible. The organizers encourage participants to stay in the right lane and stop at red lights: "We need to show drivers and fellow riders how to share the road by stopping at red lights. It Gives More Time to Party! While stopping at a light, say hello to your neighbors, make a friend, and dance on the street! There is no reason to be in such a rush when it just means more time to party."

What could go wrong with that?
