The Central Valley is a large, flat valley that dominates the central portion of the U.S. state of California. It is home to many of California's most productive agricultural efforts.
The Central Valley can get very foggy in winter, making driving extremely dangerous with visibility of 100 feet and less. On the faster highways such as Interstate 5 and State Route 99, the fog can turn small accidents into smash-ups of dozens of cars.
Gang activity is quite common in the larger cities. Avoid being out alone after dark, and avoid wearing solid red or solid blue, as these are gang colors and may make you a target.
