Its one thing to be helpful and have it be appreciated and quite another to be rudely rebuffed for trying to prevent someone from damaging their rig, let alone campground property. We saw a guy at Grand Canyon Railway CG in a very nice Newmar pull out and rake the side of his coach on a post at the end of his site. The wife tried to warn him and get him to stop BUT...the look on his face was like a mad man and was not about to listen to anyone. He had to have done thousands of dollars of damage to his coach. Oh well. How do you help people like that? Its not that people get their jollies from watching others misfortunes, its just that some people don't want to acknowledge their "stupid".
I'm sure he probably sued the campground for his stupidity.
