How to avoid the Chicago railyards... put the trains on ferrys and take them across the lake, and the SS Badger is the last of the coal fired steam engine powered ships that were built to do that, which makes it part of US Highway 10, and M-90, and a National Historic Landmark (thank you Brad!)

The trains hauled cargo, like Wisconsin dairy, beer, and meat, (Remember, Green Bay Packers were named for the meat packers!) lumber, paper, tractors and Nash cars across the lake, and in the other direction, Michigan produce, chemicals, salt, car parts, and vehicles
