One possible route. Google Maps and Mapquest both tell me to take I-90 across South Dakota when I plug in Grand Rapids to Yakima, but I’ve never been to North Dakota and would like to check that one off my state list. Thus, I’m leaning toward toward turning up toward Minneapolis and then taking I-94 across. And actually when I force Google Maps to make that my route of choice the result seems to be a trip that is thirty miles shorter and also slightly less time consuming. (Click the blurry image below for the actual interactive map.) Any suggestions from those of you who have driven either of these two routes? Either way it’s thirty plus hours of solo driving.
