A few summers ago, I had the opportunity to visit Utah. This image is from the end of a day in Bryce Canyon National Park. It had rained in the afternoon, and this beautiful rainbow appeared just after sunset.
My dad and I showed up at one of the overlooks just in time, and rushed to the edge of the canyon, running with our tripods and gear in tow. After the rainbow had disappeared and we were retreating back to the car, the storms started moving on and raining on us.
