Its not a canned hunt by any means, but doesn't mean it is the hardest either. It all depends on where they are and what the snow does.
If they are on huntable ground, it is pretty easy to get close and do what you need to do. Unless someone beats you to the punch. Once they are shot at, they head north of the Gros Ventre for safety.
If they are on the park, you are wasting your time. And if it was like last year, a lot of time was wasted.
