it is certainly the silver lining of US devolution were it to occur. I would not mind having a greater proportion of resources going somewhere else.
the midwest has three great rivers (or 2 or 4) but they can move things, and a land that is highly amenable to road and rail, and those lakes are not that far away.
the mountain west, and the arid southwest are more problematic. UT, WY, ID, MT, CO, NV, AZ, NM ... kinda stuck, unless you refer to the higher more arid midwest, OK, KS, NE
