The Canadian wolves have been hard on the elk here and the whitetail up north are gone from what I've been told, I personally know of two Bighorn sheep herds that are gone as a direct result of one pack of 7 wolves. We find elk killed and not even touched except for maybe being ripped open, very few wolf kill get used unlike a lion or bear kill.
On another note, I had one friend hunt Wyoming this last season on a bull hunt by the park that he was able to buy since they had tags left over and he shot a 156 bull that you can't get one hand around at any point on his main beam, heaviest elk I've ever seen. Another friend just got back from Colorado from an elk damage hunt, I think he said it cost just over 200 dollars per tag and the land owner hooked them up and even took them out on snow machines, he has lots of time to hunt but not tons of $$ so he's trying to find the best hunting for the least dollars. He said he can hit Africa and shoot a pile of plains game while being put up in kind of a drop camp situation all for less than a guided elk hunt
in the States.
