I will finish work in Marquette MI on a Thursday and thinking about circling Lake Superior. Leave Marquette early Friday morning (7:00 est) Head to Ashland, then Duluth and hope to make it to Thunder bay Friday night. Is that doable? I have nithing to see between Marquette and Duluth. Waht are the Must see places along Hwy 61 between Duluth and Thunder Bay. What is there to see between Thunder Bay and Sault Ste Marie? Is that a one day trip? I am good for 300 to 400 miles per day.
