I'll be in SJC from Wed 9/8 - Tue 9/14, which is not a million miles from San Francisco. I would love to get together with people while I'm down there! Feel free to email privately if you don't want your info in a public post.
I will have a car. Don't yet know what I'll be doing that weekend; a trip to Napa/Sonoma sounds good in theory, but driving + wine = NO, so maybe not. Other suggestions welcome!
