Tomorrow, Fri the city goes a bit haywire…

• Zombiemob – 6pm – starting at market and sutter and heads towards Union Square
• Pillowfight – 6pm – Justin Herman Plaza
• Critical Mass – 5:30pm – Justin Herman Plaza
• North American Courier Championships 2007 registration day – 2-6pm – House of Shields

I don’t give a damn about the bike courier, but I do think a very short critical mass and then get taken by zombies along market is in order.

Heads up thanks to SFist “Like Dropping Mentos in Coke, Only With Bikes”
