This is part of the City of Fairfax fireworks display at Fairfax High School in Fairfax, Virginia. An unwelcome rain shower began with the flag ceremony, sending many people home. The rest of us sheltered as best we could for another hour, and the rain ceased long enough for a spectacular fireworks display.
