First of all if your coming from Cleveland, avoid I75 through Detroit. go to exit 6 and go up US23 through Ann Arbor. your first stop for the night could be Hartwick Pines in Grayling Mi. It a state Park, one of the few in Michigan to have full hookups. You can make a reservation on the the web sir. Go to Michigan.gov. Mackinaw city has Mackinaw Mill campground, nice place. Petosky, or Traverse city on the west side are great places. Petosky has a great state park or 1st class KOA. Traverse city you can spend days looking at stuff
