Shark's in the water! I love that movie!

I know that Bull Sharks have been found swimming in freshwater rivers for quite some time now, but this link really makes me thing "Could there be sharks in the OH river this far away from the ocean"? What do you all think?


The link has a funny address...but it will take you to the video of the shark in the Potomac.
