I dunno, man. A favorite shooter of mine bought herself a piece of turf in rural West Virginia and built herself a solar cabin. Her lifestyle looks awesome. Buy this book and leaf through it. Then splurge on a subscription to Mother Earth News. See if that catches your attention - it's hella cheaper than moving to Singapore. Wyoming/North Dakota are in an interesting spot at the moment because they were fracking boomtowns but with oil as low as it is right now they're kinda fucked. I have sort-of family that headed out to one of the Dakotas and they love it... but the economy, from what I understand, is not one you'd want to move into at the moment.
Appalachia is a bit of a gamble, what with coal as an industry dying a painful death and lumber and steel not being what they used to be. The mid-west is almost as inexpensive as francopoli points out and probably has a better economic safety net, Detroit being a depressing statistical outlier. That book is going on the list though. It's a good thing summer is coming around, I'll be able to spend plenty of time outside catching up on everything you're recommending me. I don't know what the rest of the economy looks like out in the Great Plains. Regionally though, it's appealed to me a ton, if only because it has such a beautiful landscape. I half think francopoli should take some of his equipment out there for a vacation sometime for star gazing. The lack of light pollution from the cities coupled with a clear night would make for some great shots. An honest part of my unhappiness comes from city living and while I'd love to get away from it, I wonder if some place like rural Wyoming might be a bit extreme. On the other hand though, if I could find myself a decent paying job out there, it might be worth it.
The fact that you want to move deeper into the Flyover States indicates beyond a reasonable doubt that you should follow your heart, not mine. given my druthers...
Two weeks. Deadliest road in Canada to get there. Primarily because it's a double-yellow 2-lane for about 200 miles and it all looks like this And you have to break the speed limit because it's so fucking fun and then you swing wide into oncoming traffic and oops there's a logging truck.
