"I once led a trip of middle school kids to the top of Mt. Sterling. At night the kids and the other co-instructor went to bed in their tents, I chose to spend the night in a hammock. I laid there enjoying the scenery and noticed something moving on the trail. As it got closer, I could tell it was a person. We were in the middle of nowhere and there was someone hiking up the trail with no headlamp. They arrived at the top of the mountain and just stopped. I watched as what appeared to be a man survey our camp. He stood there for what seemed like thirty minutes then turned and sat down under a tree, staring at our camp. I just stared at the man while he stared at my camp. This went on until about 3:30 am. Then he stood up, took a moment to survey my camp a few minutes longer and then went back down the trail he came up on."
