What do you mean? I just watched the sky and pulled over to the side of the road and took a few snap shots. . .

The clouds started off wispy but then they started looking like they were out of focus and elongated and then, it was over. . . I knew that only a wide angle would do any kind of justice, so I shot it at 12mm. I have my photogarphy gear with me ALL the time, so i'm always ready to shoot.
