There are few clubs in the Pcola/FWB area - White Sands Jeep Club, Emerald Coast Jeep Club and Jacked-up Jeep Club.
I am a member of the former but not as active as I'd like to be - seem to make about 20% of the events (like tonight's meeting). ECJC has a website and forum. I dont know much about Jacked Up tho have seem some of their rigs.
If you want to ride on Eglin - be sure to get your Eglin pass from the Jackson Guard in Niceville; everyone in the vehicle over 15 or 16 needs one. They have various types. I just got my recreation pass - I think it was $10-$12.
If you have other questions - you can ask here or pm me - I'll try to answer. THere are others locals on the forum that should chime in.
