Like I-70 is to Kansas, I-80 doesn't do Nebraska any favors either. I actually hate I-80 worse than I-70, mostly because I-80 is all the same for hundreds of miles. At least I-70 you get some change between the eastern deciduous forest, to the Flint Hills, to the ag heavy flatness, back to the Smoky Hills, and then the places where big bucks hide in plain sight.
Anyway, Nebraska is a beautiful state if you get out of the I-80 corridor. Has a lot of good scalping country.
I don't really like Missouri as a state, but the natural beauty is undeniable, the Ozarks in particular. I've spent a lot of time down there, could retire there even if I got the right piece of ground.
