Staying in rest area's requires a bit of common sense for sure, just as it does with campgrounds. We only didn't feel safe at one rest area near Chicago and did move down the road to a truck stop. But have to say we did stay at some county parks that were pretty rowdy. We have been asked by the rest area custodian more times than we can remember, if we were going to stay the night. Many times they would tell us how safe their place is with maybe being manned 24/7 or the state patrol checking frequently. South Dakota still prohibits staying more than a few hours, but we have not been awaken ever there, and we just returned from there last month. We take our Q frmy the truckers. Rest areas have come a long way. Iowa for example has WiFi at most with dump station. Some even have a little hiking trail. We are now poised to visit ky, Tenn, ark,and Missouri starting Friday for a few weeks. With the gov shut down, were just going to do rest areas while traveling and dispersed camping in the Nat forest's.
