Philadelphia to Gettysburg

S1, E105: Michael Portillo travels to Philadelphia, feasting on a gargantuan Philly cheesesteak, then pays homage to one of the city's most famous sons, Rocky Balboa. In Traintown USA, he rides on a vintage steam locomotive. Next stop is the 'sweetest place on earth', where Michael learns about the world's largest chocolate factory. His last stop is Gettysburg, the most famous battlefield of the Civil War.
