Here's an "optimal Pure Michigan road trip"
Round Island Lighthouse Mackinaw Island Michigan
Spectacular Michigan waterfalls you must see! » My last state in the continental US to see, I think a road trip is in order for this summer!
Touring Michigan's Tunnel of Trees is a delight to behold, especially in the fall.
Abandoned Years Ago; A Dinosaur Park. I was there in the 70s, it was abandoned then. NO Rides, Just Walking Thru Acres of Trails, with Life Size Dinosaurs. I wonder if it still stands, in the Irish Hills, Michigan.
