Shipwreck expert Ric Mixter headlines Great Lakes Festival in Livonia

The longest-running maritime history show in the Great Lakes returns on Feb. 28 at Livonia's Detroit Marriott. Local 4 brought in a special guest you might recognize from our documentary, "Backstory: The Edmund Fitzgerald." Ric Mixter has been investigating shipwrecks for decades, producing his own documentaries and authoring books about them, and Saturday morning, he'll be the first speaker at the 44th annual Great Lakes Shipwreck Festival in Livonia.
