About the Cities

Starting in Fontana, CA

Full guide →

Fontana is a city in San Bernardino County in Southern California.

Arriving in Pomona, CA

Full guide →

Pomona is in the San Gabriel Valley, near Los Angeles, California. Named after the Roman goddess of fruit, in the 1920s it was indeed known as "the Queen of the Citrus Belt." However, its origins preceded that epoch as an allotment given to two ranchers, Ricardo Véjar and Ygnacio Palomares, in the 1830s, when the territory was still part of Mexico. After the Treaty of Guadalupe Hidalgo and becoming part of the USA, it eventually became absorbed into the megalopolis of southern California, with perhaps its main standout nowadays being the site of the LA County Fair, or the location of Cal Polytechnic U.
