From the latest comments, I see I'm not the only one with a thing for windmills. Here's a photo of the ones I saw at the Yucatan state fair in November. It's an artless picture but I wanted to get the phone number in case I ever want to get one for aforementioned irrigation system. These are on a much more modest scale than the ones that dominated the skyline in old images of the city.
I can't see them without thinking of that ubiquitous ear worm that won the 1969 Oscar for best song, The Windmills of Your Mind. Not so sure I'd want to sit in the patio watching the windmill blades turning, with those spooky lyrics running through my head.
