A sudden burst of rainbow colors explode above the Golden Gate Bridge during the 75th anniversary celebration of this most famous structure. It's hard to believe it was opposed by a number of people at the time of its building but I think it has won most people over. The fireworks echoed off the canyon walls of the Marin Headlands only to be drown out by the loud cheering of the huge crowd that lined the hills to take in one of the most spectacular firework shows the City of San Francisco has ever seen. No one left disappointed but all left wanting more.
