we started tripping-toe stubbin, and stumbling since 1984, and from the very first day, we asked WHY? is that there???
we understand the toilets are plumbed above grade, and access may be needed....the one inch step here and there we assumed it might be to "squeegee" water out of the rooms....but even on a "yard like" grounds, all of a
sudden..."THERE'S A STEP"!...for no reason we can see....
it didnt take many trips (pun) to learn to bring small flashlights......
we would get back people would ask.."Hows was your trip"?
"which One ? was the reply....lol
