Flat country + a green environmental movement = Windmills.
Like the few in the Bowling Green's high wind zone North Dakota's landscape is dotted with the energy harvesting turbines. Grand Forks is home to a manufacturing plant for Wind Mills, and we got to see a lot of parts traveling down on the road on "Long Load' tractor trailers.
Findlay and Bowling Green each had an oil boom at the turn of the century which lead to rapid growth. It's a new century, but ND is going through the same growth pains.
Finally, like Findlay, the flat land is prone to flooding.
So really, the only difference between North Dakota and Northwest Ohio is about thirty two feet of snow that dumps on them in October and doesn't melt until May.
