I guess it's a combination of the challenge of taking a mature animal and love for seeing new country. Outside trips to the NFR every few years that I enjoy and the wife loves, I never take a vacation to an area more populated than home. I live on a ranch and work outside every day so just being outdoors alone isn't it for me. There is a drive in me to see what is over hills and mountains, or up canyons I haven't been to before, and to revisit ones I have been in before to see what has changed. I love wild country and being able to concentrate 100% about hunting in it, not worrying about everything else and squeezing a few hours in hunting on the side like around home. I love the thrill of seeing a mature animal come within range also. That moment when by planning, persistence, or luck I am in position to take the shot. I love it just as much when I'm not the one behind the gun but it was my plan that put us there. All the times my plans don't work make those times they do special.
