During the Parade of Ships for San Francisco Fleet Week, the first warship was led by a fireboat from the City. It sprayed water from its hoses to provide a focal point to the parade. As it got closer to us, the angle of the light and the mist from the fire hoses resulted in a clear rainbow forming in front of the fireboat. It looked pretty cool and I am not sure the photos really do it justice. However, here is a shot to show you pretty much what we saw.
