I was looking at a map and I just happened to see that there is a town called Columbus in Kentucky. It is microscopic, and not near anything except the the Mississippi river. Downtown consists of a very small post office and a restaurant or bar called "Jen's Place", and that's it. Next to the river is a park and a Civil War Museum.
Sometimes, I wonder why a few towns exist at all. This is even true for some places I have lived in, like Little York, Indiana.
