CB_RadioKids are rushing to become like their idols and cranking down the din to hold them in while they butter and ride park , without the knowledge of good form which can prevent injury.
Right, but the problem here is that if you make it ultra strict, then none of these kids are going to ski at all... so they'll be perfectly safe from injury because they're bored to death. Maybe they'll start snowboarding where nobody is going to stop you from shredding the park because its part of it.
Trust me - I have coached kids from a very young age. You don't need to force strict lessons and hold them back from the fun stuff to teach good skiing skills. The idea that the park is destroying skiing is a myth - held up by elitist old guys that don't want ski racing to go away.
If someone loves the sport, and they get out there every day... you can teach them form in between runs. Even if they dont' get taught, they learn as they are on their skis more. If someone skis 5 days per week with no training, they will end up better than someone who does 2 but only does formal lessons.
It will rarely even matter because the guy who does 2 days in formal lessons is either going to quit or start snowboarding.
Stop being such adults. Trust me, kids who are irresponsible know whats up way more than adults.
