He went back probably 50-60 yards. This put him right on top of the trailers. They had to get a ruling for him to mark is spot on a gap between the trailers. Then from that spot he got obstruction relief to move horizontally away from the trailers no closer to the hole. He probably went 20 yards over into the practice area. From there it took forever to get the crowd moved and even longer for his caddy to get him a line and a distance.
