S.S. City of Milwaukee

At Frankfort (foreground) and Elberta, Michigan, in 1991. The ship had recently been appointed a National Historic Landmark.

City of Milwaukee was built in 1930 for the Grand Trunk Railway, and ended her career in 1981 when the State closed down the Ann Arbor Railroad ferry operation. She sat there in the Frankfort harbor for nearly two decades, then moved to Manistee. She's functioning now as a museum.

The alert reader will notice that the two sites I've linked to show slightly different dates for "built" and "retired." Such is life, I guess.
