4 Mount Rushmore National Memorial; Keystone, South Dakota
As of the 2010 census, the population of the small town of Keystone, South Dakota, was only 337. Yes, that means that basically the whole town is dedicated to providing food and shelter to the three million or so tourists that come through the town every year to see the Mount Rushmore National Memorial. In this circumstance, we don’t blame these locals for feeling just a little hostility toward the swarms of Hawaiian shirt-clad dads trying to get a picture with their family in front of every sightseeing fixture.
