Today we drove along the Au Sable River Road Scenic Byway. The road follows the Au Sable River until it reaches Lake Huron. Stopped at a few lookouts and the visitors center. Had a nice picnic lunch at a county park. We found a road side picnic area off M23 that had access to a paved path that ran along Lake Huron. Took a nice walk. We would up at the Harrisville State Park campground for the night. Continuing our very slow trek north.
