The previous owners of our house left a few things behind, including a blue kiddie pool. We already had one blue kiddie pool, so now we have one on the basement patio and one on the upstairs deck. Pool parties abound (weather permitting).
Katie just loves to be in the water, and she seems willing to put up with the worst weather and the coldest water. Long after Scott has retreated to the warmth of a towel, Katie will still be in there, cheerfully chirping to herself while she fills a bucket and dumps it again.
