A rainbow and a sailboat at Kallavesi

I had a picture of a butterfly which had landed on my work jacket. But I and my wife saw an unusually bright rainbow while walking at the shoreline of lake Kallavesi in the evening so I prefer posting this for today. I will yet see a lot of butterflies at work during this summer.

P.S. Too bad I hadn't my better camera (and tele lens) with me. My old pocket camera's picture quality don't make that gorgeous rainbow justice.
