Desktop wallpaper

I don't know why, but after 86 posts I haven't written a single one in English... That's gonna change!
This is a short one, though. I was looking at some Flickr pictures when I saw this one. It's beautiful! I took it in San Francisco, near a huge windmill (sorry, but it was 3 years ago and I can't remember the name of the place...)
Isn't it gorgeous?
