Michael Portillo continues his journey from the northern state of Minnesota to the Deep South. Michael is in Milwaukee, located on the shore of Lake Michigan and home of the Harley-Davidson. Michael learns about the history of motorcycles there, the first of which was made in 1903, and hitches a ride on the back of a modern version. German gymnastics is Michael's next challenge as he joins the Ladies' Auxiliary Exercise Class, a legacy of Milwaukee's 19th-century German settler community which is still going strong today. In Racine, Michael discovers a man who knew how to sort the wheat from the chaff and made a business out of it.
