Hey mick,
I may have been up your way this past weekend.
I went to Grand Rapids to see the Arena game.
We crossed at Sarnia/Port Huron and took the I-69 to I-96. There's a bunch of construction of the I-96.
When I travel up to the Soo, we take the I-75.
I went with a friend who can get me any seat I want. The Rampage won, 71-65 I believe in a great finish!
I'm not really sure where the U.P. is, but being 30 minutes from Lk. Michigan, and seemingly travelling a bit north, maybe you know where I was.
