Maybe some people feel my words were too strong but until someone pointed out the perspective of the picture I honestly thought it looked like the pool was on the roof.
My wife thought it was on the roof too...
In fact she got the mail and called me on the cell phone and said, "The pool is on the roof" while I insisted it was not. So when I got home she showed me the pic and I saw what she was saying. It looked on the roof to me. So that is why I started this post to clarify this point. Now that I read the posts and look at the pic in perspective I see that the pool is not on the roof.
But it sure is a tricky pic to figure out.
