You will be competing directly with the rifle hunters, waiting for them to come out of Yellowstone National Park. Most years they never come out of the park. If they do leave the park the possibility of you getting them with a bow before the guns do are slim, at best. If you hunt the Absorkas, figure going in around twenty five miles. If you hunt the Gallatins, it is only about six or seven miles to where the outfitter line up their clients', waiting for them to cross the line.
Believe me, if I thought there was any chance at all I would be hunting the areas yearly.
