What's the WORST Experience You ever had at a RV/Camp site?

two experiences, both years ago and both likely involving copious amounts of alcohol. the first was a group of chronologically young adults who were throwing empty booze bottles againt some large rocks at the rear of their campsite (commercial campground). a report to the office was ignored so we left the next morning. the other was a large, loud, obnoxious and apparently drunk group at a state park. a complaint to the rangers resulted in their eviction.
