From the beginning of the trip, Bryson's intentions were to hike the whole Appalachian Trail. Even he didn't realize what a feat this would be. While passing through the town of Gatlinburg, they went into a hiking shop to buy new shoelaces for Katz. There was a four feet long map of the Appalachian Trail in the shop. "Of the four feet of trail map before me, reaching approximately from my knees to the top of my head,we had done the bototm two inches...All that we had experienced and done-all the effort and toil, the aches, the damp, the mountains, the horrible stodgy noodles, the blizzards, the dreary evenings with Mary Ellen, the endless, wearying, doggedly accumulated miles- all that came to two inches." p.150
It was hard for the two hikers to put into perspective how long the Appalachain Trial actually was, but this map was a rude awakening. It shocked them how insignificant their trip had been so far. After the initial shock, Byson was liberated by the idea that no one was forcing them to hike the whole trail. They decided that instaed of getting on the trail right where they left off, this time they would drive a bit so after their next hike they would be closer to the town.
This was a big part of the book. It changed their whole plans when the imensity of the trail was put in a tangible form in front of their faces. They realized what some fail to realize, hiking the trail is a choice. Some take it on as burden but really it is just for your own purposes. No one would ever know or care if you skipped some trail here or there or if you just decided that hiking the whole trail wasn't for you. The Appalachian Trail can be just for leisurly hiking, it doesn't have to be a miserable undertaking.
