I heard about that on the radio. Good find on the video. There are some good shots of the fences and crossings they put in along part of that route to cut down on the roadkill. That is some pretty good quality video. I had no idea that they migrated that far. No refuges or anything on the route I guess. The cows drift down from the mountains on their own over there, too. http://www.pinedaleonline.com/news/2004/10/GreenRiverDrift.htm.
