The JeepFliki run by PCGuy has a listing of Florida Jeep Clubs. Hopefully you will find something to your liking.

Listing of Florida Jeep Clubs

A word of advice. No jeep club is perfect. Hang out for awhile before joining any club. Get to know the people there and decide if it works for you. Never get involved in the administration of a Jeep club your first year in, it's too easy of a way to burn out. Just have fun!
