You should always discuss this with your outfitter well before your hunt. Many outfitters will supply you with styrofoam coolers and dry ice. They will probably charge you for this. Some may require you to bring your own. On many fly-ins, weight is a consideration. You may be charged, by the pound, if you are over a predetermined weight limit. Again, discuss this with your outfitter well beforehand, so there are not any unwanted surprises.
