Goat Herders on the Road

On one of my many explorations of the Mexican country side I ran into a very young girl walking and leading a herd of goats up a dirt road out in the middle of nowhere. Bring up the rear of that parade were these two men riding mules. They passed within arms length of my jeep but they didn't pay the least attention to me. I was, for all intents and purposes, invisible to them. That was a encounter straight out of the Twilight Zone.
