Wyoming! Alaska would be a close second.
Since I've been in all of the lower 48 at one time or another that is a hard choice. It would certainly be west of the Mississippi. The PA game commission has decimated the whitetails here. I'm thinking I could learn to handle cattle and shack up at that Medicine Bow Ranch until the owners get tired of me and then move on to southern Colordo around Ouray. Hunting opportunies are waaaaay better than what's in PA.
I wouldn't mind a nice ranch just on the ID side of the Tetons.
I'm not sure I believe 1 place has it all, so I'd either need a few places, or to move periodically.
I'm pretty sure I'll either end up in IL or CO. Other states are great/have their perks, but to live in forever.
My mind is a raging torrent, flooded with rivulets of thought cascading into a waterfall of creative alternatives.
