David Sadowski has been interested in streetcars ever since his father took him for a ride on one of the last remaining lines in 1958. He grew up riding trolley buses and "L" trains all over Chicago. He coauthored Chicago Streetcar Pictorial: The PCC Car Era, 1936-1958, and runs the online Trolley Dodger blog. Come along for the ride as we travel from one side of the city to the other and see how trolley cars and buses moved Chicago's millions of hardworking, diverse people.
