Count me in as a motivated maybe.
I'd start from parkmerced (next to SFSU), so probably I'll join jinws's group on the Sunset side.

Pete, just as a suggestion, could you compile the information for this ride on the first post of the thread?
It would be great to see the curren roster for each group (sunset, caltrain, sausalito, etc), the proposed route from Mike's bike (distance, elevation, etc). I think there are a couple of routes on the thread.

The weather looks so far so good (party cloudy, highs in the low 70s, lows in the low 50s, 10% chance of rain).

It will be my first time on Mt. Tam too, so I'm looking forward for another nice Bikeforums ride !
