It was getting dark and we were looking for a campsite whilst driving down the Oregon coast road. We drove into one and the guy on Reception looked at our car, saw we had no trailer. and said 'You might not want to camp overnight here'. The reason given was everyone else had brought one or more ATVs (All Terrain Vehicles' with the sole aim of tearing up and down the sand dunes all night long. There were dozens of them. It caused a great racket of noise but was fun to watch as the sand dune area was vast and restricted to ATVs. And Yes, we didn't get much sleep.
