I've been to quite a few, Toronto, Tahoe and local ones. A new group just started up in North County San Diego area and they just had a meetup last Saturday. My first was in the LA area by a young woman who left and was on her own; she ran it for a number of years. It wasn't a large group but different people came from all over.
Another friend started one up in the Salt Lake City area.
Just the best thing ever is to meet people that understand what we all are going through.
