Weeknight group rides in SF/Northbay?

Are there any regular, good (i.e. fast, fun or both) weeknight rides in SF or Marin?

I'm kinda new to the area I seem to be coming up empty handed, other than the Wednesday night Let's Ride Really Crappy Pavement in Golden Gate Park and Run Some Stopsigns Ride. Any info?

Thanks.
