Bay City, Michigan

The claim: Classic enclosure with guard towers, high fence, and close to shipping port on Saginaw Bay, which connects to Lake Huron. Could be a deportation point to overseas via St. Lawrence Seaway.

What it really is: I've taken a look at the city via Google Maps, and despite it's name, there is no shipping port at Bay City, unless of course you count the public marines and a couple of privately owned piers. Other then that and a maybe a few industrial centers, there is nothing there that resembles the claim.
