Another Way of Dealing With itAnother effective means of preventing this is continually doing small tail lifts while in line. I alternate left, right, left, right. This makes it more difficult for skiers or boarders to go over the tails. When they do, most will feel you lifting your tail and will move back. Those who don't get their tips adjusted. I don't apply a lot of pressure or do this quickly (to prevent injury or damage to others' skis) but doing it slowly is a non-intrustive way of getting their attention and preserving personal space. Works for me.
