I like seeing that the Womb in 1973 is much the same as it is now; even if it wasn't yet named the Serenity Pool, that pool is pretty much there as it is today; the creekside pool is half the lagoon sandbagged like some photos you have posted Wiz of work done on sandbag pools in the 90s. Can't quite tell if there is a pre-Arizona now Phoenix Pool there from these pics, but the rocks seem to be there….Lots of dogs, lots of kids, and a real utopian disinterest in clothes. Love it. It was 42 years ago!
