There's no meets section. There are a few bay area groups that tend to organize things. For some reason after this forum garnered enough attention to open carry we had crazy fragmenting amongst Californians. I still have no idea why this occurred.
The Responsible Citizens of California usually has something going on weekly. Their website is here: http://www.responsiblecitizensofcalifornia.org/
There's also Bay Area Open Carry, website here: http://www.baoc.us/ I think their facebook page is fairly active, although don't hold me to that.
The people on this forum who haven't bothered to join the other groups are often invited or informed about meet ups before they happen. Sometimes that's done privately, sometimes that is done publicly.
None of these groups force people to open carry in order to show up to an event. If you're new, it'd probably be a lot less stressful to just go to one and talk to people and see what holsters people have and what recorders people are using and the like. It's also a good idea to just check us out to make sure we're not all psychopaths, although everybody I've met thus far has been really cool.
