SGs in Bay area

my son wants to know if there are any SGs in the Bay area so he can get together with them sometime. He's one of the older SGs, 31. One of the first to be born. We left when he was around 15. He would like to correspond or get together with SGs in his area if there are any. That is, obviously, SGs who are not in the family. Can someone post this at MovingOn? I understand that it is a place for SGs only.
