I've only lived in Arkansas for 36 years so I hope I'm qualified to answer your question. The first 1/2 of my life was at the foot of Mt. Magazine. When I graduated I moved to the delta to go to school at ASU. I have not yet managed to leave the delta, but with God as my witness some day I will. Now, that said, when I do move, I'm not at all married to the idea of moving back to the hills of Arkansas. They are beautiful, don't get me wrong. My problem with the state is the politics. We are in the top 10 in cumulative tax rates, I'm thinking maybe top 5. We're a long time democratically controlled state and all that goes along with that. We don't have castle doctrine.
Now, me personally I'm thinking if I had my druthers, I'd look to move somewhere on the eastern half of TN. It's beautiful there, too, and the politics of TN I find to be much more agreeable, at least anywhere east of Memphis.
FWIW, I recently saw a Craigslist ad where a guy was looking to sell land near Hardy, AR for about $1200/acre.
