Query: A powerful book!

I've read this and Guthrie's other books countless times. The power and history of the story have yet to disappoint me. Guthrie captures the people, the times, and the "feel" of the west as no other author has. I grew up in the area where much of Guthrie's story takes place. When I need a dose of home, all I have to do is reread one of his books.
