Here in Wyoming proof of sex is required when you are hunting an area that isn't open to either sex. You only need a nut or a nipple on one quarter. A rack doesn't count unless attached to a whole animal. As to where to put your permit. I was told by a warden that when in transit having it your pocket is fine. One time I had both halves of my liscence with me and he told I should have left half with the meat already in the field. Only to protect your carcase from theft. If someone finds an untagged carcase in the woods and claims it. You have no legal right to it. So now I always carry the punched tag with me while packing and leave the other part of the tag visibly attached to the meat thats left hanging.
