Great American Railroad Journeys: Georgetown to Mount Vernon

SINOPSIS

On this leg of his American railroad journey, Michael Portillo begins in Georgetown, Washington DC, where he eats at Ben's Chilli Bowl, the diner chosen by President Obama for a snack before his inauguration. He also visits the United States Naval Observatory, where he discovers how and why the railroads established four time zones across the continent in 1883. As he heads south to Alexandria, Virginia, he explores a former slave market, before finishing in Mount Vernon, where he visits an archaeological dig.
