I agree with Islandman. I grew up in central North Dakota along the Missouri River and now live in the NE corner of South Dakota. I have traveled to the western part of SD several times and would much prefer the drive across ND. More scenery and towns for stopping conveniences. My wife and I are now moving to Oregon and I will be going through Yellowstone on the way but plan on driving I-94 through ND and stop at the beautiful Medora, ND and the Theodore Roosevelt NP. The route is easy driving with a fifth wheel, as well.
