I almost responded to you in that thread, I think. This is also my dream. I think maybe because I was in love with the movie Annie as a very little person and she swims laps in Daddy Warbucks' pool.
Having said that, I guess this is the part of the thread where I tell you all that the previous owners of our river house put outdoor carpet on top of the concrete pool deck (outside). It is the nastiest thing EVER, and I'm having a hell of a time trying to find a deck company/concrete specialist to pull it up and resurface the deck.
