In 'Uncommon Carriers,' author John McPhee takes readers on a fascinating journey through the world of freight transportation. Accompanying hard-working individuals responsible for moving goods across land, air, and sea, McPhee delves into the lives and experiences of truckers, ship captains, towboat pilots, and those manning colossal trains. He rides with Don Ainsworth in an immaculate hazmat-carrying tanker, explores a UPS air distribution center bustling with package sorting, and navigates the Illinois River on a towboat longer than the Titanic. With his trademark humor and insight, McPhee sketches vivid portraits of these overlooked sectors and their personnel, illuminating the complexities and vital importance of their roles in everyday life.
