Getting to Prague from the Bay area took a bit of travel time. I know, less than in covered wagon and sail ship times, but still it was into the next day, and the seat on the airplane was truly lived in. Alas, I made the change of planes in Frankfurt, but my suitcase did not—and flew on with Lufthansa into the unknown. So I arrived on a new day on a Prague afternoon with the clothes on my back and a single camera. Which I took out to explore right away. As I neared the Charles Bridge I saw clouds and maybe a rainbow forming, so I dashed up the spiral stairs in the bridge tower, added a polarizer, and snapped a few frames before my rainbow disappeared.
