Just wanted to say that out of all the books on preparing for an A.T. thru hike, Zach Davis' book, 'Appalachian Trials,' is perhaps one of the most useful! Having done a few sections of the A.T. , I already have experienced many of the emotional/psychological phases Zach discusses in his book. He writes with honesty and humor...this one is not to be missed by anyone considering doing any distance hiking on the A.T. (or any other long distance trail). Well done, Zach!
