Wolf Hunting

Have any of you guys had any luck hunting wolves? I missed my opportunity at a nice muley over the Utah muzzleloader season and I'm looking for other hunts to make up for it. I've always been interested in hunting wolves and after having a bit of success hunting coyotes I thought that I'd give it a shot. How have you found them? Are you calling them in or going out and finding them? Any info would be great, looking forward to planning a challenging hunt!
