Several places that I have camped that I did not see mentioned here are county fairgrounds, highway rest areas, and truck stops. The truck stop was with permission and I would not do it again. Truckers leave their diesel engines running all night. Some use gas powered electric generators- extremely loud and obnoxious. We stopped at the truckstop for a shower; it was late and the manager said we could set up our tents on the surrounding grass strip. Fairgrounds are perfect. Lots of out of the way places behind the livestock barns, etc. and usually no one comes around.
