Bad weather is my favorite weather to shoot in. A sky without clouds kills landscapes, in my opinion. I was standing on a very narrow shoulder of a sharp curve on highway 550 with a couple of other photographers who left when it started to rain. From experience I know that rain and broken clouds often yield a rainbow in addition to great lighting. Getting cold and wet is a small price to pay for such a brief opportunity. Due to the fast moving clouds, the rainbow lasted only a couple of minutes.
