He had food in his possession. He was on a well marked trail after having hiked 1200 miles from NY to South FL. No way he was lost. He knew how to read trails. Nobles Camp is 100 yards off an old road which is 5 miles away from a rest stop on I-75 where there is help, food and shelter. That is the easiest hiking anybody can do.
It is said people did see his tent at Nobles before he died but they did not disturb him. He could have asked anybody coming across the camp for help. He could have moved 100 yards at a time over a number of days and made the rest area. Even a rudimentary map would have shown him he did not have far to go.
Lost, not moving far, etc. doesn't make sense. He was manic somehow and chose to avoid contact and to wither away there. That makes sense. Although we will never know for sure.
Can you provide some sources for what you are saying here. I'm not saying it's false but I do think there are some assumptions. I've read a fair amount and have not encountered some of what you are saying. Where does it say he had enough food in his possession? Where is the actual map he had that shows the rest stop or where does it say he had a map that showed a rest stop where you are saying? Where does it say he was manic? I have read nothing that says he had any kind of mental health issue.
