Unpressured elk. In cowiche, could happen in december right behind the feed pens, but not during any open season. Can still regurarly snag elk meat out of cowiche, but they ain't likley to be standing still for more than a few seconds at a time. Just got to put in your time.
One tip. the biggest kill is the first 2 hours of the opening day, then the last haf of the season after the pansy hunters go home.
