My boys have a Slip N' Slide that they have played on nearly everyday. They love it when their friends and cousins come over to play with them.
We went over to visit Shane and Emily's one evening. Shane took the boys out in the backyard to play and before I knew it they all stripped into their undies and were swimming in Brooks's pool. The water in the pool was freezing, but they didn't seem to mind at all. All four of the boys were little fish that day.
