wind power

Hi.
Last week I was in southern Ca. the San Diego area. I spent the night on top of a mountain and when I got up the next morning to go into town to make my delivery. I looked across the road and this is what I saw. It was foggy and there were several wind mills on the hill on the other side of the road. The bottom is what I saw without zoom. Then as I zoomed in you could see the blades turning but only at around 3oclock and then up to around 9oclock. that was the fog line.
Just though it was pretty interesting.
