I thought I might mention the giant catfish found in our famous three rivers. These whiskered piscines find their way into the locks along the Allegheny, Monongahela, and Ohio rivers, and are trapped there. Lacking space to move, the little suckers grow, and grow, and grow, sucking up the slime on the bottom, until the reach the size of Volkswagon Beetles, which they sometimes swallow. Now, I've neve seen one of these creatures, but many locals swear they exist.
