MADISON, Wis. (AP) – Maritime aficionados will get a chance to dig into Wisconsin lighthouses this week at the Wisconsin Historical Museum. Ken and Barb Wardius are scheduled to discuss their book, “Wisconsin Lighthouses: A Photographic and Historical Guide” at the museum on Madison’s Capitol Square on April 1. The book contains color photographs, history of the state’s lighthouses and travel tips. The talk is free but the state historical society is suggesting attendees each make a $2 donation.
