As a former Army Ranger and avid hiker/explorer, 65lbs is way too much for hiking the AT. You will likely be down and out with knee or shin pain by the second week. Drop weight by losing the tent, sleeping in the trail shelters. At the most, bring a poncho, some nylon cord, and lightweight tent stakes for the wet months of May/June should you need to erect a shelter. Reduce water carried and refill every 3-5 miles at shelter wells, and lose additional weight wherever you can. Try to get to no more than 40 lbs. by mailing additional supplies to post offices along the AT. Lots of books and websites out there that can explain the supply cashe option.
