Query: Filled With Facts

The book was filled with a lot of good information for someone looking to hike the Appalachain Trail.I did have one problem with the book. I found it to be a slow read and I had trouble reading it for long periods of time. It reminded me a lot of my school text books. But if you can overcome this set back you will learn a lot from the book.The most interesting fact I found was that it costs on average $1 / mile to hike the AT.
