Last September, I visited Paris with two friends. One morning we went for a stroll through the Luxembourg gardens where I snapped this shot. I think it's pretty colorful, though the skies were cloudy.
I had hoped to find a shot of a rainbow I had taken in Pisa a few years ago but couldn't track it down.
Here's one more shot, also from Paris, but from a trip in 2006. This boat seller/renter can often be found in the Tuilleries.
