Michael Portillo continues his journey from the northern state of Minnesota to the Deep South.

Michael reaches Tomah, Wisconsin, where he helps harvest cranberries, an important crop for the US.

Boarding the Empire Builder rail service once again, he travels to Wisconsin Dells, where an innovative photographer first captured motion.

Michael takes a plunge in the waterpark capital of the world and finds a pleasant surprise in Baraboo - the circus is in town and it travels by train. Guided by a former clown and ringmaster, Michael explores the train's spectacular wagons.

Michael Portillo is blown away by the skyscrapers in Illinois's Windy City, where he discovers how modern Chicago's skyline replaced a largely wooden city, destroyed in a great fire shortly before his Appleton's Guide was published. Training with the city's firefighters, Michael learns today's fire department respond to half a million emergency calls a year.

Michael steps up to the plate with the Joliet Slammers, stars of the US national game of baseball, then sings for his supper at a quintessentially American restaurant bearing his name! Downtown at the Moody Church, Michael tracks down a pair of evangelists who toured Britain and the United States by rail at the time of his Guide.
