I'f you're down for an adventure might I suggest picking the car up in Minneapolis, then taking route 2 through the UP of Michigan on your way home. Rt 2 is a simplistic two lane road that takes you through some of the most beautiful country this side of the continental divide; you won't even realize you're driving. Of course there are downsides: repair shops are few and far between (especially Foreign), and it is a slightly longer drive then going though Wisconsin/Chicago, like I said, more of an adventure. Personally I'd take the Women and make a mini vacation out of it, the UP is downright amazing.
