Shark Attack...

...off the shore of New Jersey. The speculation is that it was a small great white. If that reminds you of Jaws, it should. Peter Benchley's book was based on a series of shark attacks by a rogue great white off the coast of New Jersey. A good account of the attacks is Close to Shore by Michael Capuzzo. In a lot of ways, the true life account is more chilling than the fictional terror at Amity Island, especially the part Capuzzo relates where the great white actually travels a good distance up a freshwater creek to attack a boy in a popular swimming hole. I don't know if I'll ever look at muddy water the same way.
