That's what they call it. More and more ranchers are not repairing the old windmills, and even tearing them down in favor of new-fangled pumps driven by solar cells. Fortunately there are still plenty of the old AerMotors around, and will be for some time. If they ever disappeared I'd really miss them. They've pumped the life-blood of this country for a long time. Some of them are now pushing a hundred years old and still squeeking away.
