Ok, after extensive research – mostly by John, we have determined that Highland Hammock State Park will accommodate all of us and is relatively close to the rivers that interest us in the Tampa area. As of 8:00, 16 April there are more than enough sites available for the week starting 8 March with departure on 15 March. I have reserved site 064. Sites 059 through 070 appear to be available, have water and electric and will take RV / Van, trailer and or tents.
We are looking at National Forest Camp Grounds for the Ocala area week. John is highly confident that he can identify one that will handle all of us. The National Forest campgrounds allow reservations 6 months in advance so we will identify and announce the Ocala and Panhandle campgrounds.
