Nogales, AZ, has been a major commercial hub for fresh fruits and — especially — vegetables entering the U.S. from Mexico for generations, and a casual glance at a map makes it clear why. Located considerably further west than other ports, such as Pharr, TX, Nogales is well-positioned for reaching huge western and central sections of the country, and is also ideally situated for key production regions in northern Mexico, notably Sonora and Sinaloa.
