I went in about 11 last year for mountain goat in MT. Hike about 6 miles that evening, and the rest the next morning. 18 miles is what he might have wound up going in total, but he could have started at 9, and just had to go back further to find game. I say, and this is just me, go in only as far as you have to. So people will even agree with this, there is good animals 3-5 miles in to Wilderness Areas, you just need to know your area. Hunt smarter, and harder.
