Retired educator Sue Hartman has been tending to the Marblehead Lighthouse for years. As a member of the Marblehead Lighthouse Historical Society, she’s involved in day-to-day operations at the Marblehead Lighthouse State Park during the season as well as fund-raising and managing the park’s lifesaving station and museum. Let’s visit with Sue to find out more about the Great Lakes’ oldest continually operating lighthouse and the group that helps keep it one of the most popular tourism sites in the state.
