I decided to go out boatwatching yesterday as well. There was another ship coming down that I wanted to catch.
I decided to head to Del Ray because I thought the ship in question was going to place nearby. That didn't end up being the case. But I did catch a couple of pictures of the Presque Isle as she was unloading at Zug Island.
The Preseque Isle is the 1000 foot articulated tug/barge but she looks like a real ship, so I'll give her a pass. She is unloading taconite.
