The environmentalist part of me loves the wide open beaches and soaring dunes around the lakes, but there is also a part of me that finds beauty in these industrial corridors.
If you've ever seen a lake freighter loaded with train cars and on some of those train cars are loaded with semi-truck trailers, then you've seen the economics of moving goods. In general, it is cheapest by water, then train, then truck.
Industry consumes the majority of electricity produced. Wherever there are industrial corridors, you will find massive power plants. I arrived in Monroe, Michigan today. Some of the largest power plants in the nation stand on the shores of Lake Erie.
