Karsten is a decent drive north of you, as is Ashton. Rick Moen is near there. I think that rcareaga is across the Bay from you. Slugbug can get to San Francisco fairly easily.
Grygus and I are, unfortunately, a little far away...
(Stuff that I learned while travelling around last year.)
Cheers,

PS I should point out that there are several more IWETHEYers in that area, but I'm not sure which ones might have moved since I saw them a couple of years ago. The economy has sucked in those parts...
