Secret swimming pool in the Mojave Desert

[WestSidePool]

So you get a key for 24 hours total and a GPS unit. It's up to you to find the pool if you want to take a dip.

I'm curious what process they use to keep it sanitized. And how long before it's location is publicized and it's not so secret anymore?

Looks like a puck floater and uh... sorry but that pool is too small for me to enjoy! I wouldn't want to tromp through the desert just to get there either. No thanks but thanks for sharing. lol

Interesting publicity stunt to make people visit his museum to get the key and gps coordinates
