We had a bad experience @ PenMar in 02 as thru-hikers. Granted, we were camped in one of the pavilions which is officially off limits, but had been sanctioned by the park dude (I don’t know his title, but he seemed to have authority). He warned us we might have teens partying (drinking we thought). Wrong-we had 20-somethings, selling drugs (and trying to buy Oxy from us-like hikers would be carrying narcotics!?) around midnight. It was one of the only times I was scared on my hike, we packed up @ 2am and hiked out. I really wanted to call back to the park after we left there and tell them what really happens after hours, but as things work on the trail, several days later when you reach a phone, it was no longer high on my list. :oh
