A Walk in the Woods: Rediscovering America on the Appalachian Trail by Bill Bryson

This book chronicles Bryson's experiences hiking the Appalachian Trail in 1996. In addition to his personal experiences, there's a lot of information about the history of the trail, and the nature and other things one encounters along the way. He's willing to push beyond the appearance of things (for example, what do the National Park Service and National Forest Service actual do with the land and resources they're protecting), and he serves it all up in an entertaining and humorous style. This book prompts some great reflection about our relationship to the natural world and to our own bodies and their capabilities. A great read.
