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.
