About this episode
Navigation is easiest when you know where you're going and you have a clear idea of where you've been. That's why the woods can be so dangerous if you get lost, because there's not much of a horizon to find landmarks from. Trying to find your way out of a cave network based on a map written by people who weren't completely accurate about where all the caves are or where they go is going to lead to getting lost about a hundred percent of the time.
