Yes, it is on a number of sites designed to defray the cost of camping. One poster spent the whole season there as all he had to do was break camp and move every two weeks. It was free. Similar requirements to BLM sites. He did so the entire length of the beach. It is my supposition that the RV was used as a cook site for meth. Similar issues in the triangle area in California. Free camping but then a biker club rolls in, takes over for a week and then leaves. A very frightening story online about it. I never knew things like that existed. Boondocking is not in my future. Yes, in order to go into Mexican interior, you need the insurance and the whole shebang. But people in Del Rio, Brownsville, Del Rio, etc. all can cross easily. Many people live/work in both areas. El Paso is the same.
