The SS United States, formerly the world's fastest transatlantic passenger liner, is about to become the world's biggest artificial reef. Later this week, the liner will be towed on its last voyage from Philadelphia to Mobile, Alabama, where it'll be stripped of fuel and other biohazards. Then it will be towed to waters off Okaloosa County, which bought the ship to give both sea creatures and divers a refuge. The county also plans a land-based museum honoring the ship's legacy. We speak with Alex Fogg, who's in charge of natural resources for the county.
