The CSL Assiniboine Passes St. Clair

It looked like it was starting to rain but I saw that I had another ship I could catch.

 The CSL Assiniboine was making her way upbound after delivering to Nanticoke.

 She was heading up to Superior, Wisconsin where she would either be picking up iron or coal.

 I suspect she was picking up iron in order to make a return trip to Nanticoke.

 She makes the turn to make her way upriver.

 A relatively clean shot.

 As she is just about ready to pass me.

 the almost beam shot.

 And the beam shot.

And she passes me.  From this point, it is about 48 hours to her destination of Superior.
