On my drive to Lubbock, just past Eastland, I ran into a field of wind-energy windmills. Several fields, actually. I've always thought those things looked a little creepy. Not terrifying, but mildly unsettling in that sci-fi sorta way.
Driving BACK through these multiple fields of renewable energy, I could not see the structures themselves because it was late at night and out in the middle of nowhere. We're talking pitch-black. What I could see were the little red lights, one on top of each windmill, to keep planes from flying into them.
Literally hundreds of little red lights. All of them blinking. In unison. Stretching for miles in every direction.
They're out there.
