41. A Walk In the Woods by Bill Bryson
My dad has had this book for a long time and has told me a lot about how much he liked it, but finally he just gave it to me to read, and it was really good. Bill Bryson is really funny and interspersed in the story of his hike in the Appalachians are facts and statistics about environmental changes and their effect on nature. I am going to check out several of his other books that our library currently has.
