I Have To Admit,

I thought these tanks were Photoshopped,

with the words, Hot, Warm and Cold written on them, but I was wrong, the story goes that teenagers painted "hot" and "cold" on the town's two water towers, when the utility company next painted the tanks, they kept the graffiti titles, and just prettied up the lettering, then a third tank was added, and it was labelled "warm, is it true? well I am not sure about the story, but the tanks are there if you follow this street view link to Bartlesville, Oklahoma.
