yeah leashes arent bad all the time. my lil buddy davis used to ski on a leashe. he was 5 at the time. hed ski without one most of the time, but we'd put one on on blacks ar double blacks, so he wouldnt get completey outa control.
but when kids are just starting out, they become to dependant on the leash, as mentioned above. the key for beginners is lots of mileage.
yeah and dont listen to those fools about snow valley, go to rabbit hill
