I have doubts that you would even be able to get to the area where he shot it. He probably covered 15 or 20 miles a day at 18000 feet mostly up and down. Look at the terrain and think a little bit before saying how easy it was! It was an easy shot, doesn’t mean he walked up and shot it, he walked all right, likely over 75 miles in horrible terrain.
