In West Coast Gatherings, you'd see an announcement if there were publicly available events. There's a private list for that event, and, public or private, all attendees are screened prior to being added to the mailing list.
If you just want to find any event, several have things attempted in General Western Gatherings.
California used to have monthly events. These fragmented into a couple of events, and then several events, and now there's one in NorCal.
Were I down there more, I'd just organize a hotel-based event or club-based event again. Munches can happen anywhere near to the club or hotel.
