Well, there is one up by one of our practice tracks. I have seen it a
dozen times, only once was it actually running and that day, it was
annoying as hell with the noise.. and it's nearly a half mile maybe a
mile as the crow flies to the mill from the track. Like I said though,
most times, it's not moving even though there is windy up there all the
time.

How big was it?

The small, fast turning wind generators like you see on cruising
boats, roof tops and small towers can make an annoying whirring noise.
The big wind farms however use very large towers with slow turning
blades over 100 ft long. They are almost silent in my experience.
