I ended up by chance joining a large group of Jeeps in driving in the July 4 parade in Cumming. I found out that the were a combination of members of NGJ and a new club, Forsyth County (FOCO) Jeepers. FOCO is mainly a FB group apparently, but they have a monthly meetup and do some easy rides (apparently Sheep Wallow quite a bit).
The Jeeps in the parade covered quite a variety from an older CJ to a couple of 4-door JKs. I did see a good number with winch bumpers and light bars, but I got the impression that the social aspect is more important than wheeling. One couple I talked to had a brand new Rubicon and had been to AOP, but only drove on the access roads.
In my view groups that love Jeeps and socialize around them make for fine clubs, and not sponsoring club rides doesn't mean they're dead.
