I don't drink while driving on the trail. While I'm a passenger? Sure, why not. Anyone that knows me, knows I like beer.
Around the campfire is the place to go and get silly. Drinking and driving is illegal, no matter how you look at it, it is against the law. Plus, I don't think I would happy with myself if I knew I hurt someone because I was drinking on the trail. That is the stupedist excuse ever.
This is not to say, that I haven't done it. But I won't do it anymore. Infact, I have been the dude to tell people I am wheeling with that I don't think it's a good idea that we all go out.
Personally, I don't give a **** if you drink and drive on the trail. Even in my group i'm not going to say anything. It is a personal decision and I am all for people doing thier own thing, whatever floats your boat. IF you get caught though, pay the fine. It was your own fault.
