PC-USA - stay away (they're probably a lost cause).
PCA and the OPC are pretty good.
I really like the Free Presbyterian Church (www.FreePres.org ) - but there aren't any in California (let alone the Bay Area) - but I've enjoyed listening to sermons from various of their pastors on www.Sermonaudio.com. Alan Cairns is excellent (as is John Greer, etc).
Re ost32, I am not positive but I think this church is a member of the Presbyterian Church of the United States, and if so, from what I have read, you’re right, it is a lost cause.
Going undercover the other night I went to their Italian dinner (just hungry) and they make excellent spaghetti and meatballs, though.
I appreciate the other suggestions and will see if I can find a church that’s a member within reasonable driving distance.
