It's just above the UP in Michigan :-D
Do a google search, and then go to maps 8-)
Hey John, I live just outside the thumb. We've been thinking about possibly launching our boat at Port Huron (we normally launch from Lexington) and taking it up an over to Lake Michigan... maybe even Chicago... Not sure yet, it may depend on the price of gas.
If we do take the trip, I'll see what it takes to get to Sault St. Marie! It would be fun to meet you!
