My favorite: ME! I get more enjoyment out of me hunting than watching others hunt.
That said, I learn from all kinds of hunters including those who don't bowhunt because I simply love the great outdoors and getting into nature. I read and learn from a lot of the great bowhunters like Bear, the Wensels, Hill, etc. I also read about Teddy Roosevelt's hunts, studies from Game and Fish research, conservation based stuff, field guides, listen to Joseph Von Benedikt, and other notable hunts/hunters. I also share in the struggles and joys of local hunters, especially children of my buddies who need a little encouragement in the field. It's much more about a lifestyle than just being a fanboy of a certain person.
