Generally, if the ski patrol is yelling at you, its because you are doing completely stupid, pointless shit like bombing down moderate groomers full of families and beginners, endangering other skiers for the sake of 2 foot airs off of the "jumps" with the blind/flat landings that happen to be right at the intersection of popular trails, etc. The funniest thing about the guys I see doing this shit is that they think that popping off of the 2-footer or straightlining down the middle of a beginner slope makes them "Xtreme" or something.
There's a time and a place for hauling ass and going big, but it's not on groomers that are jam-packed with five-year olds.
