Fans of deep-fried anything rejoice! The Orange County Fair opened its gates yesterday and will be welcoming crowds in Costa Mesa until August 3. There's tons of stuff going on there from Tuesdays through Sundays, including live performances, kids stuff, carnival games, animals, exhibits, and did we mention the food? The theme this year in the OC is "Say Cheese!" so some combination of cows, photo ops, and dairy products is sure to be in abundance. Die-hard fair-goers, consider this a primer for the LA County Fair, which runs September 5-28 this year.
