The hardest part of the AT for me was getting to the trail and going home when it was over. The data book and thru hiker companion gave me all the information I needed. I tried to get a special dog food for Winter in the early part of the AT but the post office just didn't work for me. Winter didn't have a problem switching dog foods as I anticipated that she would. Pat from Maine does more planning for us when we hike other trails. Resupply and town stops are often not as easy as on the AT. Just let your hike unfold for you...don't try to pre-write what will happen. In the beginning you may question your choice to hike the AT but that will fade as you adjust to the AT. Seasons will change and by NH or Maine you may start feeling like you've been out there forever. Don't worry about it... that will morph into a combination of excitement of approaching Katahdin and a weird sadness that the end is near. When you come down from Katahdin you will begin a strange decompression. As you recall your hike you will smile at so many things that you could not possibly have anticipated. It takes a while to get your mind around what you have experienced and you will know why so many go back again and again to enjoy "the hike."
Plan...."you don't need no sticken plan."
