Query: Bill and Katz excellent adventure!

A real fun read. Bryson is funny,determined and hopeless all at the same time.His hiking partner Katz is a combination of every hiker I've brought along my travels from boy scouts to high mountain treks. I don't know how many times I laughed out loud while reading Bryson's account of his friend on the trail. On the serious side the book is an excellent story of the bonding that occurs when people enter the woods on a hike together.You can know someone for years, but go on a extended hike with them and you'll come away with a new feeling about them. Bryson does a nice job telling about the trail, it's history, beauty & vulnerability. A must read for outdoor enthusiats.
