This past weekend, I attended a college football game at the LA Coliseum with family to watch USC beat UCLA by an enormous margin. With a kickoff at 7:15pm, the game didn’t end until around 10:30pm. That means we did not hit the highway to leave LA until 11:30pm, for the 4 hour drive back to Fresno.
During that drive, a realization hit me like a wall. A wall of fog. Bad fog. Those who think it gets foggy in San Francisco or London have no idea what it’s like to experience the Central Valley’s Tule fog, which can decrease visibility to zero.
The visibility in Tule fog is often less than 1/8th of a mile, about 600 feet, but can be less than 10 feet. Visibility can vary rapidly in any area, with sudden decreases to near zero in only a few feet. It is situations like these that often lead to multi-car accidents where one car follows another into a fog bank.
