From the hunters I've interacted with, there's a sort of convenient split. One has a lot of gear, pheromones, covers a lot of ground with trucks or atvs. Personally, I don't find this particularly sporting, but it's not really my place to judge. Some folks do (well, did, when I was a kid) this because that meat would save them a lot of money.
The other kind of hunter will only take 3-5 bullets, but tell you if they use more than one, they messed up.
From everything I've read, Roosevelt was very much the second kind. Go out in the woods. look around. Try to really understand what's going on, and figure it out. It shows in his legacy, the national parks, the conservation movement, heck, Teddy Bears are named after him.
