Water towers in Okemah, Oklahoma, birthplace of Woody Guthrie. As I understand it, they build water towers to punp us and store water in to build up pressure in the water mains in really flat places, like Oklahoma. We used to have one in the town I grew up in in Michigan, and it was like a dare when you were in high school to get over the chain link fence and climb it at night. Okemans thought Woody was a dangerous radical, til they realized his home was a tourist attraction and meant more tourist bucks for the town. People kept asking them why they had two towers, instead of one, so some wag got them to paint "HOT" on the left one and "COLD" on the right one. Then they'd snicker at the tourists who read the labels and nodded wisely.
Then their respect for Woody's fame meant they actually memeorializsed him on the modern mushroom tower they built later on the far right.
