If you have(as stated) seen glimpses of them a couple times in the wild, you are way ahead of most people.
I spend more time than most folks in the mountains and have only seen 1. He was chasing 2 deer before I let the air out of him.
They mostly feed on deer, elk, moose, so be in an area with good populations of these. They will follow/stay with the deer/elk during migrations. In the late fall/winter when the deer are all bunched up....that's going to be your best bet. Good luck!
