FL. Pretty self explanatory pics. Clearing and leveling. "Get outa there Max!" He does the same thing at home when we change the sheets. lol Palm fronds for a vapor barrier to keep the damp from coming up into the insulating material. Then starting on the grass. You need more insulating material than you think. It compacts. A long fire and a wool blanket. Temps in the 30's that night.
LOL, it does get cold in Fla. On our bug out to Ocala Nat with some folks the frost was 1/4" thick. Got cold the first night but was ready the next.
That's where I did that camp. Stay tuned for thread on 3-4 day wilderness survival camps in and near there.
