Trevor McDonald ends his trip along the Mississippi river, or as he prefers to put it, “a vibrant, liquid highway”, being hoist into the air by a couple of strapping young male cheerleaders in Minnesota. You might think that cheerleading is for perky, pom-pom waving girls, but McDonald informs us that it was once an all-male preserve. George Bush and Ronald Reagan were both cheerleaders, which is the kind of factoid that is well worth mulling over. He later visits a huge armaments factory in Rock Island, Illinois and wanders around a gigantic shopping mall, eavesdropping on a wedding in its chapel.
