My daughter also lives in Las Vegas. She has a small house near us with a pool taking up most of the back yard. Many houses in Las Vegas have pools - don't know why there are so many here and so few in Rochester, NY.
Anyway, her pool is rather old and looking worn, with tiles falling off and the color fading. She decided to have it worked on, and the first step is sand blasting the old finish off the pool and surrounding deck.
I thought the image of a guy (I think it's a guy) in a space suit with clouds of dust was interesting. At times he dissapeared in the cloud, and then the wind would blow and he would reappear.
We'll keep you posted on the progress.
