I southbound thru-ed way back in 1990 and Elk Park, NC was not very hospitable at that time. Locals had burned a shelter and (rumor had it) dumped some chemicals in a water source in the area. I was solo and when I got to the area there were signs put up by the USFS instructing hikers not to hike alone, not to stop, and not to go into town. I had a maildrop in Elk Park and couldn't do much in the way of heeding their suggestions. I got harassed by some locals outside the post office, and to tell the truth, the whole thing shook me up a bit. I think there was a situation where the AT had claimed some trail land through eminent domain and the locals were unhappy. Hopefully, that's all water under the bridge, now.
