I come up to SF every day to work, but haven't had a chance to get on the local courses! I generally play in the South Bay when i can - Shoreline, Santa Theresa, sometimes Coyote when I have a little extra cash :-)
I haven't had a chance to get out yet this year, but would love to get a round in, perhaps even Presidio?
I played Presidio many years ago (shortly after it became open to the public) and is a great track...the scorecard shows a short course but do not be fooled. With the hills, it plays a lot longer than the documented yardage.
