We were camped at Coulter Bay in the Tetons a couple a years ago. A guy and his wife pulled in with a 30'ish ft long trailer and he pulled out this construction generator. He ran it an hour before generator hours to an hour after every day. These were pullout sites so he started out with the generator behind his rig (so it would make less noise in his site). Next day he moved the generator about 30 feet further from his rig, and closer to our site - apparently too noisy for him so lets make it louder for adjacent sites. If I'd had some cable cutters, I'd have made a disconnect for him. Probably should have removed and hidden his cable. Apparently his trailer's batteries were bad because he'd connect his brake/light cable to his truck when he wasn't running the generator. The morning I was finally going to go down to the campground office I found he'd hooked up and left.
