A drive across the arid high desert of southern Arizona brought the crew to the border town of Douglas, population 17,000., where Mayor Robert Uribe discussed creating an environment of unity with his sister city across the Mexican border.
After a walk along an 18-foot steel wall at the Douglas-Mexico border, we headed 45 minutes east to visit with Dr. Gary Thrasher, a large-animal veterinarian in Hereford, who showed us a different kind of border “wall” — a six-strand barbed wire fence and steel barrier in the San Rafael Valley.
