Most California fairs have a designated place for agriculture, somewhere like the ag building at the Big Fresno Fair. This building holds examples of the vast array of crops the Central Valley, and some other producing areas around the state, provides to the rest of the world. Often fair-goers in other states don’t get to see this type of bounty and unfortunately some California fair-goers don’t see it either, with their focus on horse racing and fair rides.
According to the Encyclopedia of Chicago, “The American county fair was developed in the early nineteenth century when agricultural reformers in the northeastern United States organized local exhibitions to promote modern farming. Typical events included livestock judging, exhibits of new agricultural implements and techniques, and plowing contests.”
It’s safe to say other attractions now draw the crowds.
