Seek and you shall find. There is always some place to lay it down for the night in privacy, minus the comfort of a shower perhaps, but good for restful sleep. Highway 90 in N. FL is great, however, look farther south and see another main road going east and west. Look at the gulf coast and see 98. It is flat but somewhat longer than 90 and the other highway. 90 is more interesting but not necessarily. 90 has more opportunities for free camping than 98, and 90 people are used to cyclists more than elsewhere. 90 deteriorates at the border of Alabama at Pace. A campground might let you take a shower for a few dollars. A $15.00, 10 by 12 foot, poly tarp is more versatile than any nylon tent. I have used a tarp on many thousands of miles of camping-touring with good results. Fire up some mosquito coils and that problem is solved. There are those little battery-operated repellents too. I have heard of designer repellents, e.g. one drop does it, but I have yet to see any. A light-weight length of rope and some aluminum tent pegs will let you string your tarp between trees. Aluminum ten-poles will let you set up without trees. Attach four-foot lengthis of poly-line to all grommets on the tarp, and you are good to go. Have you ever been in the middle of nowhere with a drving rain and tried to set up a nylon tent? It happens. With a tarp just throw it over yourself while setting up. You will stay dry. Try that with a nylon tent.
