The Laura Van Enkevort and Barge Joseph H. Thompson

 As I was taking pictures of the Alpena, I noticed that there was a ship unloading at the stone dock in Marine City.  Normally, I wouldn't be able to get pictures of that but the drone lets me do it.

It is the tug Laura Van Enkevort and barge Joseph H. Thompson.  The Joseph H. Thompson used to be pushed by the Joseph H. Thompson Jr. which was a barge made from the Joseph H. Thompson ship.

I'm not sure if the Laura Van Enkevort is a new build or an update of the Joseph H. Thompson Jr.  Either way, I've not caught her in this configuration.
