While you're waiting for your year to thru hike, or, to give back after you've completed a thru or section hike, consider volunteering a week of your time on one of the Appalachian Trail Conservancy's Trail Crews. You'll meet a diverse group of fun people and maybe get some ideas for your thru hike. Check out this link: http://www.appalachiantrail.org/crew...09-6ccdf2ca88-
I did 4 weeks of crew the year before I thru-hiked the AT and now have nearly a half year of crew weeks. I'll be returning this year and for as long as I'm able and the ATC will have me.
