Ocala is my vote. We haven't been there in ages. Might be interesting for 4 groups to enter the forest from North (Palatka), South (Paisley), East (DeLeon Springs), and West (Ocala)...we could all meet at a somewhat central spot like Silver Glenn Springs on the west side of Lake George. The object would be to use as many forest roads as possible and limit paved roads inside the forest to "out of necessity" only. If you wanted to give it another twist each group would be required to cross a river or creek and provide a photograph of the group crossing. This can be done from all directions.
