this is exactly... EXACTLY what I ran into last time I was up there- down to the asshole dad that did the same thing.

This is why it's a bad idea to advertise a nice place to shoot. Don't tell your friends... Don't tell your families. Don't tell anyone or superdad and the county commissioner will come there to shoot some dirt.
