Ok, here is some rampant speculation... I submit that most of that piping is for plumbing the splash zone. There is no way skimmers are going to need that much volume. I also notice that the kiddie pool has a push broom in it, suggesting that it is not going to be demo'ed? Why sweep it out if the backhoe is gonna crush it? I also noticed that they have broken out the coping around the main pool. Why remove it separately? Inquiring minds want to know!
Folks at the Fort, Please, if you hear a backhoe running get some pics. Pretty please. Or, as Pete would say, Pweety Please! LOL
