Back in the ’97 I was camped at Bon Secure Bay, off Mobile Bay in Alabama in my ’67 Trade Wind. (1 photo at http://www.airforums.com/photos/show...871&original=1
) I was parked next to a new Avion next to a couple in their ’80s, fulltimers. While I was setting up, the husband came over to me and started conservation. He said that they had recently been is a park in Florida where there were mostly park models and there were organized activities, clubs, etc… he said, “We had to get out of there. That place was full of old folks!”
The point (at last) is that they served as hosts at state campgrounds regularly and camped there free. There is a commitment, but worth checking out.
There seem to be a lot of members from Houston and the Piney Woods. Surely someone closer to you will chime in.
