I was also up there over the weekend and Saturday night and Sunday morning they were going crazy, I hiked down into a canyon Sunday morning and had 6-8 bulls bugling around me and one sounded like it was only 150-200 yards away so I split the distance with him and cow called and he came right in--he was a decent 340-350 class bull, but hearing him bugle at about 30 yards was enough to get my nerves going!!!!!
