South Dakota gets credit for doing the most with the least. I cannot believe the marketing moxie of this most barren of our 50 states. The Corn Palace in Mitchell and Wall Drug are boondoggles that were created simply to convince people to come visit are interesting only because of their preposterous marketing. You are in the middle of nowhere the whole time you are in South Dakota. . . and you need to stop at these places simply to take the car off auto-pilot.
