Just a little reminder that the Chihuahuan desert can be a dangerous place. I was driving toward the Chisos Mountains and noticed ahead of me what looked like a traffic jam. As I got closer, I noticed the truck was a National Park Service truck. I drove slowly and glanced to the right side of the road to see one very angry snake lunging at my car as I passed by (look at the lower left of this photo).
In my single-minded pursuit to photograph the beauty of the park, this was a reminder to me to be ever-observant of the more venomous side of the desert.
