It is indeed wondrous to discover a submarine able to navigate the locks and dams of the Mississippi River unnoticed and then lie in wait at the bottom of a muddy creek only to be pulled to the surface by a fisherman in a kayak.

I really wish they had published the brand of fishing line he used, because mine always breaks when I try to pull up anything heavier than a submerged tire or shopping cart.

PS - there is a submerged submarine, whereabouts unknown, in Illinois: https://en.wikipedia.org/wiki/SM_UC-97
