The first Cape Cod beach I remember was in Dennisport. It was the Sea Street Beach. It was not that far from the cottage we rented from my dad's sister. After Dennisport we stayed in a cottage in Chathanm. Most of the time we would go to Hardings Beach. Once in a while I would go down to the Oyster Pond.
My parents own a cottage in Dennisport at Chase's Ocean Grove. I've been visiting there every year since I was little. Nothing like Sundae School ice cream!
