getting trapped inside a park

For several years I hosted at a campground with three loops, the first of which was limited to 28 feet (for good reason). There was a sign at the entrance saying 28 foot max, and only once in the 4 years I was there, did somebody make that mistake. I was sitting at my host site admiring my campfire when in came this dually pulling a utility trailer that had to be in the 34 foot range. Biggest utility trailer I've ever seen. By then he was well past the point of no return. I stopped him, and learned he was looking for his group. He did manage to get all the way around, using the entire road, tree to tree (only a couple of which were "brushed"), and having a couple folks move cars and stuff. Took a while, including a wee bit of backing and filling, but he made it.
