It would be a really good idea. Just because you are in the middle of the woods does not mean you cannot do harm. People have been seriously injured by their own fellow huntsman, people have been fatally shot while under the influence of alcohol.
Most states already have laws that prohibit the possession of firearms while intoxicated. I enjoy hunting, but I believe 100% that guns and alcohol should never be combined! You can enjoy them separately, but don't mix them.
