The book starts with Bryson explaining his curiosity about the Appalachian Trail near his house. 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.
