Good Club in the Bay Area?

I’ll be moving back home to the bay area, specifically to Oakland or Berkeley, come this May. I want to join a club that will be a good fit for me. I’m 26, an all-grain brewer, and I have a pretty sophisticated palate. I’m interested in a club that’s fairly social, but takes brewing seriously, as well. And I want to be able to enter frequent club competitions.

Advice?
