Some lean mean swimming machines are making their debut at the Arkansas State Fair. Its the only traveling shark exhibit in the country. A 5,000 gallon tank holds four sharks...and one brave diver. Colby Cheney actually gets in the tank with the sharks...but he says theyre harmless. "Sharks arent man killers. They arent going to kill you at every chance they get. Sure people get bit on occasion, but usually its their fault for messing with them. Or they mistake you for something else," shark swimmer Colby Cheney said. The exhibit is located across from the Arts and Crafts building and is free to the public.
