I'd second this suggestion. Basically you're flying into Chicago to hit Minneapolis. If you start further out west, you can see more and drive quite a bit less. I haven't been to Yellowstone, but from what I've heard it can get busy during the summer, as in bumper to bumper through the park, so plan accordingly. (maybe others can corroborate).
