Ah...another angry skier. First off....snowboarders don't "snowplow"....skiers do. Second....."hop skiing" does far more damage to the terrain than any snowboarder could ever do.
It's been my experience that when snowboarders slide sideways down the mountain, which they occasionally do, it doesn't really scrape off the snow so much as it's simply smooths it out. You could probably think of us as an army of community minded mini groomers. Seriousy....do you think that skiers don't disturb snow on the mountain? Where do you think mogels come from? I see very few skiers using their edges....most are swishing there tales around pushing snow just like the boarders. That argument about boarders ruining the snow is so old and lame....can't we just let it go. Please.
I'll leave you with my favorite T Shirt quote..."A day without snowboarding is.....well......like a day on skiis".
Have a great day, Miguel
