When in the Michigan UP at the Soo Locks, make sure to tour the "Valley Camp" Great Lakes freighter that has been turned into a floating museum ship. You are allowed to tour the ship on your own, and almost all areas are accessible. The better part of the cargo hold has over 100 exhibits, including an Edmund Fitzgerald exhibit.
Here are a couple of pics from my tour of the freighter.....,
