Show Notes
On this day in 1965, Michigan made the unique Petoskey Stone its official state rock, with a historic signing attended by Ella Jane Petoskey, granddaughter of Chief Petosegay. And in 1958, Governor G. Mennen Williams dedicated the Mackinac Bridge—the world’s largest suspension bridge—linking Michigan’s Upper and Lower Peninsulas.
