We were there last summer, but were limited where we could go since we had the pups with us. Hadn't been there in years.
We have to drive that loop every time we go there. My Dad took his first real vacation to Glen Arbor so he has to tell the story each time, and his favorite winery for cherry wine is nearby. I've just always loved the dune climb - but then really how can kids not like it? And that just sticks with you.
