Rainbow!

2006.09.21 18:15hrs- I was walking home along Commercial Drive for ten minutes before I looked up and noticed this rainbow. I can't remember the last time I took a photo of a rainbow. This one was only a half an arc. It was sunny on the other part of the sky. Hmm, I should have taken a picture of the whole scene. You can see a second, fainter, rainbow near the top right corner. I wonder if there are always two rainbows?
