Bonus!

As I was tracking the Roger Blough, I saw that another ship was leaving the Rouge River.

 That ship turned out to be the Lee A. Tregurtha.

 She had just finished unloading at the Rouge Steel Mill and was on her way back to Marquette.

 It was kind of nice to see her since I wasn't expecting it.

She approaches Belle Isle and passes Windsor.

Her profile.  And I decided to head off.
