Mom @ Sleeping Bear

That's my mother, looking out over the Sleeping Bear Dune in 1973. Dad took this photo with his Argus C3, and I scanned it from a slide. That much I know for sure. What follows is speculation.

My best guess is that this was shot from what is now called Pierce Stocking Scenic Drive, but which was then called Sleeping Bear Dunes Park. I think the view is across Glen Lake, generally toward Glen Arbor.

As I say, speculation. But there really aren't all that many places you can find a view like this, and fewer yet with picnic tables.
