driving back from work in nogales today, we ran into a cloudburst in green valley. a beautiful rainbow formed off to the east, then became a double rainbow, and briefly a triple rainbow, which i have never seen. the two ancillary rainbows faded and the main one grew brighter and more intense. i noticed i was able to see nearby trees through it. it got brighter and brighter and closer and closer until it stretched from the hood of the truck in a complete circle back to the rear door. absolutely spectacular! i was at both ends of the rainbow simultaneously.
