No kidding. On Monday afternoon I was leaving school, and stopped at the traffic light just outside our parking garage. I saw the cloud and, since the light had turned to red just as I got to it, and it's usually pretty long, I whipped out ye olde (antique) iPhone and quickly snapped the picture--thinking that it'd be good wallpaper for the phone.
I turned it off and set it down, looking up to notice that the light was now green--but because of the fraction of a second of extra time it took me to get rid of the "camera," my left turn into traffic was delayed.
Good thing, because just as I was about to pull out, some jackass came shooting through the red light at about 50 mph. If I had actually gotten going "on time," I wouldn't be posting here today, and despite Vera's nifty side air bags and terrific frame, I'd undoubtedly have ended up as a smear on the road, given the speed at which I'd have been hit.
So, thank you everyone, for being such inspiring skywatchers that I can't pass up a good cloud, in hopes that I'd end up with something worth posting. In terms of composition, etc., this ain't much. But it did save my life.
