Good posts above.
BTW, your display shows you only being 16. Are you Doogie Howser (before his latest announcement of course), or were you home schooled? At 16 I was in the 10th grade and I had a hard time getting a pass to take a whiz...much less a 5-6 month pass to hike the AT.
Either way good luck! Did you ever decide on an axe?
