介绍：Bear drops into the swamps of Florida's Everglades, where at least 60 tourists need to be rescued each year. He trudges through the swamp and shows how to construct shelter, deal with razor-sharp sawgrass, get out of a muddy sinkhole, avoid alligators and rattlesnakes. He eats frogs and cooks a turtle Seminole-style.

介绍：Part 2 of 2. In Patagonia, Bear skins a hare, scales a cliff, tracks a puma, drinks dirty water, and crosses the Perito Moreno glacier, a vast frozen labyrinth of ice caves and crevasses.
