are any of you allowed to bait?
When I lived in west central Alberta for awhile, the best way to get em' wa to bait em'.
It was always best to wait until there was over 2' of snow on the ground, but more was better. dig a path in the snow off a road or game trail being used, wolves dont like the deep snow any more than we do, so they will follow. dig some cow/deer carcases into the ground and put some water in the whole (keeps the dogs there longer). have your stand 200 yards out minimum. walla! wolves on your bait (OK not that easy, but it sounds good).
I have often wondered if it would work to dig paths in the snow, simply to get them to use a route, even if you arent allowed to bait it. that way you might get em' using a route you choose.
*disclaimer* i have never shot a wolf, but have set up baits with people that have.
