Ok, I know this sounds wacky, but I remember my late grandfather and I once, while stump jumping for bluegills and redears in one of the many old strip mines left over from the coal era of that region, once made a comment about seeing something move off a beaver dam in crystal clear water that appeared to be an octopus. Yes, an octopus. We both dismissed it, even myself at the age of 12, but since then I've heard of more and more instances of this occurring, to where they've almost gotten a cult following by the cryptozoological crowd, of which I'm loosely affiliated [I read the newsletters, but bury them under the Musky Hunter and the In-Fisherman when company comes over]. Makes me wonder...I wasn't even aware they could exist in freshwater to begin with.
