Thank you, Thank you, Thank you to the Appalachian Trail Museum for posting this guide in full:
34. If you think you've had it with the Trail, give yourself one last chance. Hitch into the next town and get a room in a motel. Stay there for two nights. If, after that time, you aren't missing the Trail and what's going on there, then it is time for you to go back home and set your sights onto something else.
