We spent time climbing dunes, playing at the beach, shopping, and trying out the local restaurants and ice cream parlors. We had no agenda or schedule and just went where we felt like going. It was great! It was a bit cool by the water and the there was a high wave warning. The kids were apprehensive about going in the water at first, but eventually braved the cool water.
When we got home to Fort Wayne, we didn't want the fun to end, so we went to the zoo. Sunday evenings are the perfect time to go... small crowd & active animals.
