When we went as a family in 2009, I was just 8 weeks pregnant and Brendan was 3. We spent the days throwing rocks in the Straits and exploring the island's fort. I think Brendan threw about 1000 rocks that weekend. Free entertainment:)
This past weekend with our now family of four was spent throwing rocks in the Straits, playing at every playground in the Mackinaw area, and of course throwing more rocks. Lower and Upper peninsula:) All accomplished in one afternoon/evening!
