Seniors 62 and older will have one last chance to view the Robert Moses exhibition for free. Land of Moses: Robert Moses and Modern Long Island is a comprehensive study of one of the most important public figures in Long Island’s history. Come and see how he transformed a once sprawling farmland into this island we call home. On display in the Visitors Center. Museum is otherwise closed to the public. Free admission for seniors 62 and older. Senior Tuesday is sponsored by Jefferson’s Ferry, Long Island’s premier retirement community.
