Spent a day visiting a couple places in Michigan’s thumb that I had never visited before. We spent a few hours at the Octagon Barn (https://www.thumboctagonbarn.org/) just outside of Gagetown. Did not take any pictures there but the website can fill you in.
Then we traveled about another ten miles and spent some time at the Sanilac Petroglyphs Historic State Park. Just a small place with about a 2 mile hiking trail and the site of Michigan’s only known native American Indian rock carvings. You can visit the DNR website here for information on this state park: http://www.michigandnr.com/ParksandTrails/Details.aspx?id=490&type=SPRK
The website has the better pictures, but here are a few I took along our walk:
