Home walls in the North Bay?

I recently moved to the North Bay from Berkeley, and am missing the close proximity to the gym. I'm wondering if anyone has a home wall, woody, or even just a campus board that they wouldn't mind sharing with a responsible and respectful fellow climber?

I'm living in Fairfax and working in San Rafael, but anything closer than Berkeley or the Presidio would be amazing. I'm happy to chip in for holds, clean, help set, bring beer, or whatever else.

Thanks!
