Santa Cruz County: The smallest county in Arizona is home to agriculture’s most used international port of entry. In fact, more than 50% of the United State’s produce enters through the Nogales port each year. In Patagonia, cattle ranchers have done well by allowing their livestock to feed on the oak grasslands and the terrain found above 4,000 feet. Sonoita has served as Arizona’s Wine Country for the last four decades and continues to produce bottles of wine that rival those found across the sea in France. You will also find the oldest Quarter Show Horse in the country at the Santa Cruz County Faigrounds each year. It may be small, but this county generates $9,501,000 in agriculture each year.
