Wine, Whiskey, and God help me!!
I keep beer and wine in main camp in very limited quantities. It is available to you at the main camp.
I don't encourage its use in spike camp but rather as a nice break in main camp, between and after hunts. If you want something additional or absolute assurance that the previous group of hunters has not consumed my supply then feel free to bring something of your own. Personally, I rarely have a drink in camp since I am ultimately responsible and I do the flying. You can never be sure that an emergency won't arise.
