Whats the diffrence between him useing his stunt ramps etc and others. Whats fair for one is fair for all. In other words you cant single him out and say you cant do it but this guy can. doesnt matter if he is 15 and others doing it are 18 that are doing it. So get with the director/rangers there and tare the ramps etc apart. Its the director/rangers call though not yours. You can report it or not your choice. But if the rules state no one is to try stunts etc in the park regardless of age then rules are rule. If they state 18 and older only then report the younger kid.
