The second night we spent at a boondocking spot in the Apalachicola NF, south of Tallahassee. We found this spot through Day's End and we loved it. Buckhorn Hunt camp is just a open field 2 miles off Hwy 267. It is free camping for anyone except during hunting season. Then you need to be a hunter to camp there. We were the only ones there - very quiet and beautiful.
On our third night in florida we stopped at Village Pines Campground (Passport America) outside of Inglis. I wanted to see the manatees and heard that this was the area.
