Ducks in a swimming pool

During our paddle boat excursion, we went by the swimming pool. The Central Park swimming pool is a section of Iroquois Lake that has been walled off and the bottom paved. The part closest to the wall is the deepest, and not many swimmers go there. To be honest, the water is quite cold; fed directly from the city's main water supply. Besides that, it's mostly children who swim here and they prefer the shallows.

Well for some reason known only to them, the ducks like it here. Maybe they like city water better than pond water? I sure don't know, but it's fun to see them floating in the pool like that.
