Scott, we had a small children's swimming pool that they could really swim around in. They were so much fun to watch diving around. It was more difficult in the winter, since they didn't have swimming water. We sometimes took them up to the hosue and filled the bathtub with cold water to give them some swim time. Now that we have birds again, it is so tempting to get some more. However, I don't think I have the time to add another species to my list of activities.
