A good sense of humor! Be honest with yourself on your abilities and choose your hunting partner carefully. Not a place to figure out you can’t pack 130 lbs of meat or that you can’t make multiple trips after you shoot one. Not trying to lecture or dissuade you, but I have had conversations with other guys doing this trip just to find out there trip was ruined due to how tuff it was or their hunting partners couldn’t hack it. The hunt is totally doable and myself and my buddies have done it several times, but I have also seen it break people too. I even tell my self everytime on the pack out that I will never do it again, but every year I find myself right back out there. Pay attention to the weather, you will most likely have creek crossings that may be fine when you head out but be totally blown out on the way back if it rains. Trekking poles make a huge difference. A good shooting stick can be helpful as sometimes it’s impossible to get a good rest or prone shot. Choose your boots wisely and bring blister tape. Extra socks as your feet will get wet (sweat or water). Good lightweight rain gear will be helpful. Depending on time of year bug spray will be a must. Lightweight folding saw is helpful if you will be staying out there for a few days. If you are successful, you can cut willow brush and pile it up to keep your meat off the ground. A lightweight tarp is helpful to put over your meat to keep dry. Be prepared for any weather. I have spent many days walking in sunshine and tshirts just for it to drop down into the 20s at night. A GPS or inreach is a must. For the most part it’s easy to find your way, but there are also times when the fog rolls in and you won’t be able to see 30 yards and that can set in for several hours at a time. I’m sure there are some other things, but if you have a good attitude and are able to push through some crappy hiking you will have fun.
