Ruin skiing?
So you mean that if someone does a rollerblade grind on skis, then all snow on the ground will miraculously evaporate, chairlift cables worldwide will simultaneously snap, and the feeling of skiing will become a nauseating experience for anyone who tries it?
Maybe you should start a movement to create a vast army of soldiers who will take up sentry position at every known rail in existence, and they can interview anyone intending to hit those rails in advance about which grind they will be performing to ensure that it meets your approval, thus averting such a disastrous outcome.
Really, please do it because I love skiing and would hate to see it get ruined.
