Query: Reads like a letter from a friend on the Appalachian Trail.

Mrs. Twitty describes her experience hiking the Appalachian Trail one section at a time. Although this is her first book, it reads like a letter from an old friend who shares every step of the 2,160 mile journey from Georgia to Maine finishing at the age of 63, after eleven years.
