"There' one!"

I slammed on the brakes, pulled a 180, and sped back to--to another rock. Another 180 and we were moving westward again. The last "turn" had brought the false sightings up to Five. Five times we had thought we had sighted a round-tailed horned lizard, Phrynosoma modestum, basking on the pavement and five times it had been a rock or a piece of flattened vegetation.

I had about brought the old car back up to 65 mph when Jake screamed again. This time I didn't turn, I merely stopped at roadside and told Jake "Go get it." He hopped out, ran back a couple of hundred feet, and stooped to pick up another "rock." But unless he was taunting me he usually didn't pick up rocks. Maybe--just maybe...

By the time Jake had returned to the car he was grinning from ear to ear. That last "rock" actually was the horned lizard we (and especially he) had wanted so badly to see.

We had failed to find a round-tail on the first 10 of the 12 days allocated to this 2015 trip to the Big Bend and had begun to wonder whether 2015 would replicate 2014's trip when we had not found the species. We no longer had to wonder. Success, finally!

Now to find my camera.
