Continuing on the Long Island Railroad to Queens, Michael investigates the site of an ambitious engineering project that will transform New York City's rail network. A model town built by an Irish immigrant who became one of the richest men in America is Michael's next stop before he heads to the island's Gold Coast. There, Michael relives the fun of the roaring twenties at Oheka Castle, a vast private residence once home to a rail tycoon before becoming a weekend retreat for New York City's garbage men. In East Hampton, Michael discovers Home Sweet Home before ending his journey at the Montauk lighthouse on Long Island's easternmost tip.
