Nope, I don't drink at all, ever. I don't mind if people take a couple of beers though. It is supposed to be a relaxing time so I'm all for a few drinks if they want them. Of course I think they should wait until night time around the campfire.
When I used to go with all my friends yes we did do some drinking but now I go with my family including my kids so no I don't drink. Actually, I don't hardly drink at home either now that I have kids!
