Have you read some of the scenes when he worked as a fire lookout in a tower in the North Cascades Mountains in Washington?

True story: I worked for the US Forest

Service in that area and, one time, my truck broke down on the North Cascades Highway. I had to hitchhike home and while I was walking with my thumb out, I saw the exact tower in which he worked and wrote up on Mt. Hozamine. It was an incredible moment for me.
