A dusty lens can be a cause for concern, but the flares of sunlight scattering from those particles can make for some rainbow-y lens flare. Paired that with the fallen trees and friendly ferns of Muir Woods National Monument. Instant fairyland!
I live above a four-way intersection, and see three or four big crashes a year—typically from drunk drivers who run the red light. This particular night, however, saw insanity in the intersection due to a multi-hour power outage. The normally orange-hued nighttime tarmac was, on this night, lit only by headlights, emergency flashers, and road flares. It was all very strange, very surreal, and the perfect subject for a photograph.
