I just went camping in Colorado one week ago in a remote campground, my son put a twenty into the envelope thing instead of a ten, so instead of paying 17.00 for a night, we paid 27.00. Well, the next morning, we decided to go over to the next campground six miles up the road where the host stays. He said he would meet us at our campground as he had yet to pick up the payments from the tube thing. When he came he asked how many people had been out there, in other words how many sites had been occupied, we counted six. He said only three had filled out the paperwork, many come in later at night and leave early, not filling in any info to camp for free, so.... not saying this is the case here, but it shows how it can happen and there would be no record of someone even who had camped the night. When you go into the restroom/outhouse, they have a paper in there, it shows when the host comes daily to clean it and to collect, so gives you a timeline to dupe the system.
