Grew up with a backyard pool was great fun being able to cool down whenever you wanted day or night and also when my own kids were young was convient to take them to parents for a swim also, down side as already commented my Dad was always cleaning pool backyard surrounded by trees prob should have had a cover. Not sure if you live close to beach or local pool but only thing would probably be once they become attracted to the oppposite sex in bikinis, them and there mates are prob gunna give the backyard pool a miss for bigger and better things that you dont get to see in the backyard pool like white pointers etc... haha
