3. Swamp Tech

It's a great American wilderness–millions of acres of wild, primeval land with its own people, its own technology…and its own rules. Survival there depends on smarts and science, guts and grueling work…and a unique approach to one of the world's most uncompromising environments–swamps. Watch an assembly of the distinctive airboat, then hop on board for a breathtaking journey and discover the surprising history behind this swamp staple of transportation. Take a wild ride on a big-tired swamp buggy, and taste test some local delicacies that bring new meaning to "acquired taste." Witness a massive engineering project to divert the mighty Mississippi River, and meet the machines that make that job possible. Plus come face to face, literally, with enormous pythons and menacing alligators.
