Been there. The Whitefish Point Museum is a tear jerker. In the city of Sault St. Marie, there is a 'grounded' freighter for tourists to walk about. In the belly of the hold is a ripped in half lifeboat - from the Fitz. http://www.thevalleycamp.com/
Now imagine navigating a 800ft. freighter thru the Soo Locks in adverse weather. Really cool to watch from the observation platform!

When you say Michigan, the first thing that comes to mind to out of staters is Detroit, sorry to say. There are some nifty places to visit.

From the second link (which I will return to):
Why are the cameras on delay?
A. For homeland security reasons the US Army has asked that all Web Cams associated with the US Army be on delay. If these cameras are not placed on delay they are subject to possible shut down.
GOOD TO KNOW!
I have to see it.
Pretty cool link. They have movies of the previous days passages through the locks (time lapsed).
