I do to....... In July & August.....
Two summers ago we drove the 65 Coronet up through Tenn, Ky, Ill, Wi to the UP of Mich. (back roads all the way), and then toured from Iron city to Copper Harbor, Munising, White fish point, St. Ignace & Mackinac Island. Then over the Mackinac bridge and down the Lake Mich shore and across to Detroit..... Then back home to Alabama..... 3400 miles in 10 days.
Upper Michigan is one of the most beautiful spots in the US, IMHO. If you ever get a chance to go there.... take it....!
