Believe it or not this "wannabe pool" was in the backyard of a house we looked at today. Reminds me of the Clampett's ceeeeement pond except this was just a hole dug in the ground with a black rubber (?) liner that was "installed" in pieces. And I think that the structure behind it was intended to be a Hawaiian style hut. Hey, this house hunting stuff is an adventure.
Hope this gives you a chuckle!!
