Guys, listen to dogonjon. There's not an instructor on this board who didn't cringe just from reading the thread title. If your friend asked you to remove his/her tonsils, and you're not doctor, should you just cause they did the asking? (don't tell me the analogy's not apt, both "operations" can put your friend's life in danger.)
Load of crap. This ain't a black run at Snowbird, or even Vail for that matter.
I usually have people take a lesson. But, to be honest one of the main reasons I do so is so that I can get an hour of skiing in prior to baby sitting a noob on the novice runs.
Legitimate question here: Are there any statistics about first timers who take a lesson from a pro vs. non pro or no instruction who get seriuosly injured on the slopes?
