Called ahead. No answer. Arrived late. Pulled in to a spot. A few minutes later a police type SUV rushed up to me, lights flashing and bright headlights in my eyes. A very nervous acting, hostile officer shouted "put both hands on the wheel". She asked if I had a res and I tried to explain there was no answer when I called, and that I was hoping to camp on the open site and pay in the morning. She said my vehicle was not an RV and if i didn't leave immediately she was going to cite me. I tried to explain how my Subaru Outback was indeed rigged up as rv (built in bed, self contained toilet, refrigerator andfood prep area and more). She was so uptight and adamant that I leave I doubt she heard a word. Scary encounter. All I wanted was a safe spot to camp for the evening. Rude, hostile encounter that was absolutely unnecessary.
