We are heading to unit 171 or 161 this year for 2nd rifle. Start running stadiums now! If by the time you leave you can run stadiums for 45 mins straight with a 40lb pack you will enjoy your trip far more, that's my goal every year. It is an awesome experience and if you get in shape and have a good trip you wont be able to not think about going back every year. I pre-cook all of our meals, vacuum pack, and freeze them before we leave as this really helps the long days of hunting. We camp at the base of the mountain usually and plan on 2 hours to walk in and 2 hours out everyday so it makes for a very long day. We usually meet for lunch at a central location and discuss what we have seen for the day adjust tactics and then break back up for the evening. We try to buddy hunt where 2 of us are 100-200 yards apart for safety. Buy the best boots you can afford 3 months in advance and break them in, as well as a good backpack with a scabbard. Sock liners, water, and a good flash light are invaluable as well but the key in my opinion is pick your hunting party wisely! Do not under any circumstances take a pessimist, whinner, or anyone who is lazy and not in it for the greater good of the group as they will ruin your trip. Ideally find guys who will be just as happy that you kill a bull as if they do, because when you do they will have to stop hunting and help pack meat out for at least 3-6 hours depending on where you kill it. The hunting is hard but if you do it right you will make memories you will never forget. The sights, alone are worth the trip.
