I admit, I had some problems with this month's theme day. I couldn't find any recent photos that I liked, so I went back to the archives. There's nothing quite so ephemeral as a rainbow - especially a double one! I shot this one with my iPhone back in July after a quick, but heavy shower on the golf course. I imagine we'll be seeing lots of rainbows today, but I hope this one brings you a smile. For more ephemeral images, click here.
