These are the water storage tanks in Bartlesville, Oklahoma. We pass by them often when I take My Darling Husband to and from the Tulsa airport, visit family down there, or are just in Bartlesville for shopping. The lettering on the tanks is amusing. If my picture is too blurry (I was in the moving car when I took the photo. No, I was not driving.) to read…one says Hot, the middle one has Warm written on it, and the right one is for Cold.
