Not long after you leave those nooks you're back out in the flats more typical of these parts. I took time to explore historic Mackinaw City, where Lake Huron meets Lake Michigan, before braving the famous, swaying Mackinac Bridge, the longest suspension bridge in America. I'm not exactly clear why the Mackinac (pronounced Mackinaw) Bridge and its anchor city, Mackinaw, can't share the same spelling, and when I asked, the locals, in their endearing Upper Peninsula accents, couldn't explain either. I'd heard a trip by ferry to the wildlife sanctuary of Mackinac Island was a worthy way to spend a day, but I had too many miles in front of me. I would have also liked very much to explore Sault Saint Marie just to the north, and the southern shore of Lake Superior, which I've heard is a fantastic extension of this loop for those bent on shopping for memorable scenery.
