this is one of my pet peeves. if you're cutting across the trail you should be VERY aware of what is uphill. i understand its ultimately the person downhill who has the right of way, but the downhill person has the responsibility to look uphill before making erratic moves such as cutting across the entire trail. you wouldn't change change lanes without looking behind you...would you?
Even though I ultimately take the blame for what happened to me today your quote made me think about how I feel the skier was riding, basically taking up a good portion of the hill with sweeping long and slow turns.
isnt it bad form (I guess I want to say rude) for someone to take up the whole run or most of it when the hill is packed with people? If I did that I would think I would be causing a hazard making a whole lot of people to have to avoid me making a dangerous situation.
