4th of July Fireworks
Wow, they do know how to do a fireworks show in San Francisco!
They actually had two shows running simultaneously: one near Pier 39 and the other in front of the Aquatic Park. I bet the people in Sausalito had a amazing view on the twin fireworks.
I read somewhere that the San Francisco 4th of July fireworks show cost $200,000, paid by the Convention & Visitors Bureau. That's only for the show, not for the police force and the cleaning afterwards.
