I thru hiked with a guy named AWOL in 2003. He wrote a book about his hike a year or 2 after. It is "Awol on the Trail" and it is a very good read. At Trail Days he had a stand and was selling an AT guide he wrote. As it turns out it was co-authored by our very own AT Troll. How these two hooked up is beyond me since they live very far apart. Anyhow if interested check out thier website. http://www.appalachianpages.com/
It is much more like Wingfoot's guide rather than the data book.
