The Huron Lightship historically served as a navigration aid for ship traffic leaving Lake Huron and entering the St. Clair River. It is now permanently "docked" in a park along the St. Clair River in Port Huron, Michigan. The park is located at the base of the Blue Water Bridge. This is a great place to stay and watch lake freighters up close. We were amazed at how blue the water is. Of course, the region is called "Blue Water", but it really is something to see. On a scale of 1 to 5 stars, we give it 4 stars. P.S. Close by is another museum housed in an old train station. It is famous for a former railroad employee, who worked there as a youth - Thomas Edison.
