I think the best thing to take with you is a large dose of Common Sense. Just a few do’s and don’ts that I aspire to are:
(1) Don’t camp near roads where vehicles can get in close. The closest I’ve ever camped to an access road was a mile or so and maybe that’s too close…I usually pick up the step when I cross these areas as well.
(2) Keep signing the logs and books that you come upon on the trail and in the shelters. God forbid you’d have an injury …but you’d be easier to track if you left a record (but not a lot of info on where you’re goin…just where you’ve been).
(3) Leave an intinerary with someone you trust…I actually have more fun by myself…you do run into AT crazies…but it’s usually the good kind of crazy…the kind of crazy I am…the other scary crazies you can dodge and stay away from…camp is eay to break…and for the most part you can hide and do stealth camping when necessary.
See ya on the trail.
