the editor is right US 2 is super slow. It took me about 9 hours just to get across the Upper Pennisula of Michigan one summer.(lots of Rv's and Boat trailers) I-90 and I-94 (S.D. or N.D.) are not that much less picturesque than US2. North Dakota is pretty much the same wether you do 2 or 94. I personally would do I90 and hit yellowstone, glacier, badlands, rushmore etc. You can cover more ground and still a variety of beautiful landscapes and scenery.
