The article author describes her experience of traveling on Camino Real, America's first highway. Pánuco is the birthplace of Juan de Oñate, the last of the Spanish conquistadors, whose hand likely had more influence on the American Southwest and northern Mexico than that of any other single explorer. In 1598 Oñate blazed the Camino Real de Tierra Adentro, a trail that became the most used and most significant route of commerce and culture for 300 years. At its peak the Camino Real ran 1,800 miles from Mexico City north to Santa Fe. Spaniards used the trail to settle towns and villages all along the way, Franciscans used it to spread their gospel, troops from the U.S. and Mexico used it for waging battles and building forts, Indians used it to fight the swelling tide of foreigners, and traders used it for commerce.
