"Gary, Indiana, is at the lower end of Lake Michigan, 26 miles southeast of Chicago. Sometimes called the "workshop of America", the Calumet region within 16 miles of the center of Gary encompasses 25% of the steel production in the country and includes the largest single steel-producing facility, that of Inland Steel Company at Indiana Harbor. Altho the region's local transportation is now by bus, the city was once the center of several interurban and local street railways."
