For the most part I’d recommend driving up the eastern Michigan side of the Lake Michigan. Crossing over the Mackinaw bridge, visit Mackinaw Island. Next cross over to Lake Superior and drive along the lower shore of Lake Superior. Lots of small resort towns, scenery, a few waterfalls and lighthouses. Pictured Rocks National Lakeshore is worth seeing and for hiking visit Isle Royal National Park — Island (might need a permit). Continue rounding the Lake. The road and shoreline going north of Deluth to the Canadian boarder is very beautiful. You could alternatively go up-to Sault Sainte Marie then drive around the top of Lake Superior (Canada). Lots of woods to see and a few towns in Canada. You’d be in more wilderness areas. It takes about three days to drive around Lake Superior. The best side of Lake Superior is on the lower side (Upper Michigan and Wisconsin) and on the west side (Minnesota side). You could also continue traveling down the western side of Lake Michigan into Wisconsin to the City of Green Bay then explore up into the Door County (good scenery). Try to stay off the interstate if you want to see the Lake. South of Green Bay are midsized towns more industrial areas than tourist areas.
NOTE HOWEVER (!) WINTERTIME IS NOT THE TIME TO VISIT THESE AREAS UNLESS YOU’RE INTO CROSS COUNTRY SKIING OR SNOWMOBILING. TEMPERATURES ARE USUALLY WELL BELOW ZERO (F) IN UPPER MICHIGAN, WISCONSIN, OR MINNESOTA. Most tourist places are only open from June through September. Scenery is still pretty in the winter but it takes a Northerner to appreciate the cold.

With their larger lens mount, could Nikon now look at entering the medium format camera market? Is the opening large enough to use with such large lenses?
