I'm actually just about to finish Peterson's "Man Made of Elk". It's a solid read and well worth your time, but in my humble opinion, a little long on the "campfire philosephy". Peterson's views and insight on traditional bowhunting vs. the modern Outdoor Channel view of hunting, are absolutely spot on. He "gets it" and can put it into words better than anyone I've ever heard, and I wish he devoted more time to that subject. But, his spiritual beliefs and resuting worldviews are vastly different from mine, so I'm rarely on the same page with him philosophically, though his musings are certainly interesting and thought provoking. His intellect and thoughtfulness are without question, and I would LOVE to share a campfire with the guy. Just my unsolicited 2 cents...
I also just finished a more recent work of his entitled "Going Trad". Also a solid read and well worth you time.
