The U.S. Gulf coast stretches for a thousand miles along five states — Florida, Alabama, Mississippi, Louisiana and Texas. This episode features the Biloxi Lighthouse — which now stands in the middle of four lanes of traffic in Biloxi, Mississippi — and the privately owned Aransas Pass Light Station in Texas. At one time, Texas had more than 50 lighthouses to mark its long and dangerous shoreline. Today, only a few remain in reasonably good shape and most are in private hands.
The Great Lakes, which have long served as an important liquid highway, are the busiest inland waterway on the planet. This program highlights the many lighthouses found along Lake Ontario, Lake Erie and Lake Huron.
