Both cities of Nogales, “Ambos Nogales,” rest side by side along the border between the United States and Mexico, and each day thousands of people cross the border and commerce is conducted across the border in various forms. These two cities rest in two different countries, but the economies of both cities are intertwined. All photographs were shot on the weekend of Feb. 8-9, 2014 in Nogales Ariz. and Nogales, Sonora.
