Driving home to Mukilteo last night, I noticed the rainbow but couldn't stop to photograph it. My first available turnoff was near the airport and led to the Historic Flight Foundation building.
When I got where I could stop and see, I notice the rainbow directly on top of the Control Tower for Boeing. I had my camera with me and seized my lucky shot moment in the sun.
It pays to be prepared as I always carry my camera ready to go at all times.
