OP,
Boozed up hunters... I have seen ugly things and was told others, enough to now control who I hunt with. For you to write about it shows similar concerns.
Years back I was hunting with good friends where hunting was secondary. For some of them, getting together, away from family, work & problems was the right opportunity to let it loose. If they made it to the bush, they were reeking booze, cigar if not wacky tobacci, their clothes were filled with kitchen odors (small camps with insufficient ventilation) and noisy sobs. If they made it to the hunting spot, they would fall asleep and snored like diesels. So much for being stealth. I stopped hunting with them. I love a good party but when I hunt, I mean business. I fill my freezer almost every years, they don't.
We all know how unpredictable intoxicated folks can be, ranging from full vegetables to full retards including violent behaviors. Firearms don't blend well with stupid, sooner or later...
Bottom line is you have only so many days to hunt. To return safe and successful, choose your partners carefully and make rules clear. And for the records, yes I will gladly have a beer and/or scotch at the end of the day but there is discipline and control.
