beg to differ my freind,I have killed a 21 inch white-tail,and a 31 1/2 inch mule deer.I have yet to get my 350 class bull,I have just about ran down every hill here in Montana in search of him,from the Madison to the Beaver Head,and up from the Abasokas to down the Cabinets and a little patch of the rockies called the Bob Marshall in between.I have one more place to go down in to the dust bowl of the Missouri Breaks(when I draw my tag),but I will not give up hope,sooner or later we will cross tracks.
That may be your case but I am willing to wager that its not the case for most hunters. YOu can buy a 350+ bull just go to an Indian REservation or shoot one in the Missouri Breaks with a bow or draw a rifle tag there(highly unlikely) or limited tag units or states like AZ or NV... Most trophy Mule Deer hunts don't end up with 35" bucks at least not the ones I know about. I have been on hunts where there were opportunities for a 30+" muley but It would have taken more time and money then I had to hunt them. Coincidentally I have seen larger Mulies on Public land vs Private Land. Consider yourself lucky getting a 21" whitetail on your terms that is as tough an animal to hunt as there is.
