If you're a Dick Proenneke fan, you'll really like this collection of his writings, wonderfully edited by John Branson, a Park Service historian. You can read it free on-line it here. It contains a detailed biographical sketch. I was interested to learn that he had a J-3 Piper Cub from 1975-1976. He and his brother Raymond used it to explore the Twin Lakes area. Proenneke eventually crashed it (iced carburator) but crawled out to a highway and survived. He was also considered a mechanical genius by those who knew him. You can buy the book on Amazon. Thanks again to Rob Hanson for evenfallstudio.com for pointing me to this in his October 22, 2010 post there.
