Of course, when you are on Cape Cod you will have a chance to swim. Even though the water was very cold in early summer, the children did not have any problem to jump into the water. For adults, it generally needed some time to get adjusted. My father had never swum before in any kind of water, lake or ocean. He had never learned how to swim, but he was interested in watching the kids play in the water and on the sand. He even sat on the beach to feel the fun. That was quite an experience for him.
