Ironfur Steelhorn Where Art Thou?

I have been waiting a long time for this elusive bugger. I "almost" got to him one time and that was when I took a 5 minutes break just to see his dead carcass right next to me when I came back to the screen. Very nice timing...NOT. In Wowhead there are comments and suggestions about killing all the Ironfur herds around to get a spawn of the rare. I have been doing it and I saw people killing them as well but I don't see any spawn. Did Mr Steelhorn packed his bag and left town??
