Clouds and rooftops

dsc_1730NIKON D40X (170mm, f/11, 1/250 sec, ISO100)

I was coming back home when I saw that clouds, with the classical cauliflower-like shape (quite unusual in autumn season), and when I tried to look at them with the camera, I saw the red of the rooftops, which  I did not noticed very well previously, so I included them in the picture.
