If there is one thing a skier should not do, its drink and ski. Skiing while intoxicated is incredibly dangerous. Skiing involved coordination of the entire body, and the slowed response alcohol can provide and severely limit your ability to ski safe.
When you ski, others are relying on you to stay safe to help them stay safe. Drinking and skiing puts not only yourself at risk but creates a hazard to all those on the mountain with you. Be safe and save the drinking for after your finish skiing for the day…and even then, do it in moderation, as no skier wants to start his or her day with a hangover!
