San Diego had a spectacular fireworks display that lasted 30 seconds on July 4th, 2012, when the Big Bay Boom show went up in smoke all at once. A computer glitch and/or virus may have caused the ignition of all the fireworks.
The three major firework shows in Silicon Valley were no different with a low cloud cover obscuring the night sky. Depending on where you were in San Jose, Santa Clara and Mountain View, you heard the huge air cannons go boom, fireworks go shrieking into the clouds, and bright lights flashing inside the clouds. A very muted celebration since the holiday fell on Wednesday this year. Surprisingly, at my apartment complex, no one was shooting bottle rockets off the balconies.
