Is there a reason why shipment on the Mississippi River is not being utilized?...........
There is crude moving on the Mississippi River.

Or the Great Lakes? The only ports I'm seeing are in Chicago and a couple on Lake Erie. I'm wondering why Duluth/Superior isn't a major hub, since its port is well known among Lake sailors, and it's relatively close to both the Canadian and North Dakota fields. Granted, winters can be daunting on Superior, but it would seem hard to beat for a fair-weather port.
