A decommissioned lighthouse off Cape Fear in North Carolina needs help. The structure is rusting out and sinking into the Atlantic. Trask and his crew work on ropes, suspended above shark infested water. A stadium in Charlotte, North Carolina, needs a bit of love. It was once the last free-standing dome in the world, but now its corroding catwalks and rooftop need some maintenance, all on the eve of a big ice hockey game.
