... and then talk to us about safety.
as dad's, do you think we would let our kids go out if it seemed at all sketchy?
oh, and by the way, the two boys in the above mentioned link have been skiing and snowboarding since they could walk, and can out ski most people I know on Telemark ski's as well. They also climb, whitewater kayak, kitesurf, (n. shore maui) etc etc etc
do you kite?
it's cool to be concerned, safety should be all kiters first priority... but waiting til 15 years old? i know, as a dad, that by the time they hit 15, they are emotionally, and in a lot of cases, (including my own) physically gone, into teenager land where your opinion about safety doesn't mean squat.
keep your kids close. TEACH THEM THE SKILLS... and enjoy
