Ok this was a new one for me, My son and I hunt late archery elk in the unit 335 and I have hunted that unit since it opened in the early 80's. This last Saturday we were into a group of about 35 to 40 elk and up on the hillside a small bull started bugling, my first thought was a small spike showing off because he just figured out he could bugle and then a very deep throaty bull up the ridge a little more started bugling. they continued for over 2 hours and we could still hear them as we walked out in the dark. I have heard them a few different years in early November do a bugle or 2, but never like this, they were bugling like every 4 or 5 minutes.
