Done my share of Drinking and Driving while underage, just in my car that is. Lucky I never did anything that killed me or anyone else. Gave up drinking for the Lord about 2 years ago now, not because I had a problem, but because I realized that nothing good comes out of drinking any amount and I have a family that looks up to me. Needless to say, drinking while riding never existed for me, since I only got my license this year. Even if I did still have the occassional drink I can say I would never do it before getting on my bike. All one is doing is compounding the risk that you are already taking when you ride.
