My daughter drew this hunt about seven years ago with 3 points when she was 13. You will shoot in order, based on the tag number. It was in the teens and below, 7 degrees opening day during the first week of December. After shooting the cow bison (Rachel) we hung it in the ranch barn, skinned and quartered it. We let it hang over night to cool (freeze). Returned the next morning to haul it out. The ranch manager will give you all the needed info when you arrive and you'll get a G&F info packet sent to you before the hunt.
Things to have on hand;
Several tarps for keeping meat clean while cutting/quartering or wrapping quarters or the cape for the ride home, should you not need ice chests.
Bring a few friends, take turns cutting and thawing out your fingers. Extra help goes a long way.
A vehicle or portable winch, they're really heavy. Tow straps or heavy rope are helpful. a quad ramp or similar to winch it into the truck.
Several sharp knives, sharpener or a replaceable blade knife with a couple dozen blades.
A portable propane heater if its cold, the wind can be brutal up there, helps thawing the fingers in the barn.
A small generator and a sawsall with a few extra clean blades, longer is better. Everything froze, making bulk cutting difficult.
If you don't cut and wrap your own meat, line up a butcher before the hunt, Dan Bix or Casey's are both good. We used Dan Bix and completely satisfied.
Several extra large ice chests if you're going to cut it all up and take ti home or a butcher outside of flag.
Then all the usual stuff too.......Maybe a back-up rifle.
Best of luck, cows eat better than the big bulls too.
