Byron,
I live in Oceanside CA. In my log I have KM6CPF , David, lives in El Granada, San Mateo county. Memeber No. 2609
Also I have a few contacts in my log that have participated in the clubs contests that are from ARRL section EB. KB6LFM, Bill, AB6MB Jeff, and AA6EH , Adam. They are not members but they might be interested. I don't see any from the SF section in my log. I hope that gives you a starting point.
Been to the "SF" Bay area, got to be careful not to confuse anyone, a number of times. In-laws live in Berkeley CA.
Good Luck,
Bob KK6KMU
