Went to Kentucky last week, and saw the shortest creek in the world, aptly named Short Creek. It comes out of a cave from the base of a cliff, goes about 100' and disappears into the cave in another cliff. It's a neat little creek, with a surprisingly deep hole in the middle! This is a panoramic picture of it. Just thought others would find it interesting.
It is on private property, but it's right next to a public road, so anyone can stop there. Our friends in Somerset, KY know the property owners.
