That's how I was envisioning such a trip.
Best option really would be to drive from St Louis take Marine Atlantic to Newfoundland. Plus I'd knock off the last remaining states east of the Rockies (by the time I do this trip it'll be the last remaining lower 48 lol) I haven't seen in Vermont, New Hampshire, Maine.
Then I'm done with the states! woot, I can move on to better things. haha
