A long drive through sagebrush dotted prairie. We are moving on to Flaming Gorge Utah. Our route follows the Green River valley just like the Pronghorn route to their winter range. Some 60,000 of these clown-face painted creatures make the trek starting about now through October. It is supposedly the largest/longest land mammal migration in North America and second in the world only to some on the Serengeti. We saw lots of little clusters of the guys along the way. We also encountered at least a half dozen road construction areas where they are actively building underpasses for the Pronghorn. They are putting in high, continuous fences to keep them off the road but that really messes with their movement. Route 191 is a busy people corridor right through theirs (sort of unfair-they have been making that trek for hundreds of years). Anyway, hope the underpasses work.
