Seems like the assumption has been that alcohol in camp equals drunks....
Our camp is above 10,000 feet and we hunt our butts off from before dawn to dust. We enjoy a beer upon return to camp and great wine with the meal. No one has ever been hung over and not answered the alarm the next morning. It' s called being mature responsible adults.
If you enjoy a nip after a long day in the woods, you just need to insure that you take in sufficient fluids as appropriate (water that is) to avoid dehydration. Alcohol will have a dehydrating effect on you.
