These windmills are not technically in Lubbock, but are actually in a small town about 15 minutes away (where the aforementioned race took place on Saturday). These two windmills, plus another that was behind where I was standing, provide electricity for the town's schools.
I am not a native of Lubbock, nor even of Texas. I was born and raised in Greenfield, Indiana, spent a couple of years living in Glasgow, Scotland, and then landed in Lubbock where I've been ever since. Have a look!
