Thats good to see Chucky.
Yes there used to be a problem with hot tubs too.......suction drains at the bottom of the tub.
There was an incident here, I remember, when a young girl with long hair, went under the water in a hot tub, and her hair got sucked into the drain and she was unable to pull herself free, and drowned.......terrible terrible terrible.....
We have had laws about hot tubs here for quite a while.
