The book starts with Bryson explaining his curiosity about the
Appalachian Trail near his house. After buying special leakproof tents, packs, a portable stove, packaged food, and other equipment, he and his old friend Stephen Katz start hiking the trail from
Georgia in
the South, and stumble in the beginning with the difficulties of getting used to their equipment; Bryson also soon realizes how difficult it is to travel with his friend, who is a crude, overweight recovering alcoholic, and even less prepared for the ordeal than he is. Overburdened, they soon discard much extra food and equipment to lighten their loads. They encounter other interesting hikers along the trail, some of them annoying, and one flirtatious obese woman at a laundromat. After hiking for what seemed to him a large distance, they realize they have still barely begun while in
Gatlinburg, Tennessee, and that the whole endeavor is simply too much for them. They skip a huge section of the trail, beginning again in
Roanoke, Virginia. The book recounts Bryson's desire to seek easier terrain as well as "a powerful urge not to be this far south any longer". This section of the hike finally ends (after nearly 800 miles (1,300 km) of hiking) with Bryson going on a book tour and Katz returning to
Des Moines,
Iowa, to work. In the following months Bryson continues to hike several smaller parts of the trail, including a visit to
Centralia, Pennsylvania, the site of a
coal seam fire, and eventually reunites with Katz to hike the
Hundred-Mile Wilderness in
Maine, which again proves too daunting. Ultimately Bryson hiked about 40% of the trail. In the 21st century, about 25% of
thru-hike attempts are successful. Bryson quotes the older figure of 10%. At the time of his attempt to hike the Appalachian Trail, Bryson was aged in his forties. == Writing process ==
