Few years back we were on our way from Chicago to Texas. We left after work on a Tuesday and got just west of St. Louis when we decided we were tired and started to look for a place to stay. We pulled off the expressway when we saw a campground billboard. It was late about 10:30PM when we pulled in and the office was closed and no one around. We decided we'd find a spot and pay in the morning. We set up and went to sleep. We woke the next morning and after coffee packed up and headed for the office. It was probably like 7:00AM and again the office was closed. I grabbed one of thier brochures and figured I'd call and make good on the fees with the credit card over the phone. I called three different times during the day and never got an answer or answering machine. After that I figured I had made an honest effort to pay and never tried to contact the campground again.
