Although the books and Youtube videos all say that the Appalachian trail is well marked and that it would take an idiot to get lost on it, I find the thought of hiking 2,000 plus miles without a map and compass a bit foolish.
So, I bought a compass and watched a few Youtube videos on how to use it.
This is not something I feel comfortable relying on the Internet for, though many people believe that if it's on the Internet, it must be true.
With that in mind, I have signed up for a one day class in October through REI on how to use a compass and map.
Might be fun. Might be daunting.
