California Couch Crash

Well, it’s official. The Consolation Champs California Couch Crash™ will take place from Saturday August 11 until Monday August 20. I’m taking suggestions for cool things to do in SF. That is, in addition to visiting with interesting blogfolk. I know all the major things I have to do (Golden Gate Bridge, Golden Gate Park, Alcatraz, Ghirardelli, Chinatown, cable cars), and now I’m looking for less obvious delights, along the lines of the quirky Musee Mechanique (thanks for the suggestion, Cory.) Any ideas?
