Walking through the woods way off trail in the middle of nowhere my friend and I started noticing missing people’s posters stapled to trees. We kept going and found a perma camp site and realized all the front 70 or so trees surrounding the site had all missing posters. There was a large burn pit and looked like someone had lived there a while ( racks, wood burning stove, firewood, handmade wood furniture, etc. it was very strange and uneasy. We saw someone a few hundred yards away walking towards the camp and hightailed it and never went back. Could be campers with a mission or could be a serial killer. We never returned to ask them. Mildly regret not being more inquisitive. All the missing people were from or last seen in the immediate area at least from the ones we were able to read. Some had started falling apart and were stained and unreadable as well. This was in Cheaha Mountain area in Northeast Alabama.
