The fudge factory in Uranus, Missouri has a lot of great t-shirts and magnets. Just make sure you turn the right way when exiting the highway because Uranus is one way and Dixon is the other.

There was a place in South Dakota, somewhere near Mount Rushmore, where optical illusions made it look like a ball rolled uphill and chairs could stand on edge. Can’t remember thr name of it, though.

If you’re driving a road trip in the Dakotas or thereabouts, do not bother with Wall Drug.
