A Coast Guard reenlistment ceremony was held Friday afternoon in the two hundred eighty five thousand gallon shark tank at the aquarium on Roanoke Island. Petty officer second class Chuck Anderson signed on for another six years with the coast guard in front of a sea of fans and surrounded by four sharks and dozens of fish. Anderson volunteers at the aquarium and thought reenlisting underwater would be unique. And no, he's not afraid of swimming with all those sharks. Chuck says he's been scuba diving for twelve years. He was certified when he turned twelve.
