21 Keel Cape Drive, Yarmouth, MA, Massachusetts 02664. Remember the 'fun' house growing up? It was the one where everyone was welcome, where all the best parties happened, and there was always something to do. The house at 21 Keel Cape is that house. What's on the docket today? Take the boat out from the Blue Rock Heights association dock? Maybe head up to the pool instead. Or get a wiffle ball game going in the big back yard. Need a snack? Come up on the deck to the kitchen door and then back out again. At the end of the day, with multiple common areas on the first floor, there is a space for every mood: Rip it up in the big kitchen and dining room, watch the game in the living room, or have quiet conversation in the den. At the end of the night everyone makes their way upstairs to one of the four ample bedrooms for some rest before you get up tomorrow to do it all again.
