@Linkat,
Since you started this thread, I've paid a little more attention to those pools around here.
They're all over the place, no fences, just sitting in the backyard.
I would think there would be ordinances on that, maybe code enforcment just isn't paying attention to them.
I wonder if the figures in the report aren't lumped together, a 5 year old should be able to prevent his/her drowning in one of the small wading pools.
That's why I thought they might mean the larger type.
