I did a driving job over in Sun Valley for a large philanthropic group. They had a couple of biologists riding around on a ranch with them for a couple of days. When the subject of sage grouse came up, the biologist in my vehicle said roads on the prairie were a very big issue. The local rancher in the vehicle immediately disagreed and I had to add my two cents as well. Jackson Hole airport has a devil of a time keeping the sage grouse off the runway, and I see tons of sage grouse crossing the roads while I'm antelope hunting or just cruising the prairie. Roads don't bother sage grouse in the least.
