VICINITY OF ANTIQUO MORELOS, Tamaulipas, Mexico -- We drove through the much of the night on our final run back to the United States, stopping a little after midnight to camp in eastern San Luis Potosí. Later that morning, we entered Tamaulipas and drove until about noon, stopping to eat and collect.
I saw a huge lizard -- more than three feet long, in the cliff below, but when I told Don and Richard about it, they did not believe me. I pestered them until they followed me to the site, and they saw the lizard, too. We tried to catch it, but it did not cooperate.
