After reading about a few season ending collisions (and narrowly avoiding some myself, I have decided it's time for a public service announcement.
This is a public service announcement.
Please consider the following scenario. You are carving nice turns down a fairly steep run at high speed. You gradually come up on someone also making turns at a high speed, but not as high as your speed. You, knowing the Skier's responsibility code, immediately consider slowing down, even though you are reluctant to do so. You observe the other skier carefully. Not to worry, he is making nice turns on the right side of the run; you are making nice turns on the left side of the run. During one of your turns you make eye contact, and exchange a look of understanding: he will continue to make turns on the left as you make turns on the right, at least until you are well ahead of him.
Your Jedi mind-reading skills have been compromised by your strong desire to believe that is what the look the other skier gave you meant. What it really meant is, "I am the ahead; if you come any closer, I am going to cut you off, force a collision, and thereby teach you a lesson about skiing etiquette."
This is especially applicable if the other skier is large and not displaying high skill, despite his high speed. He has likely come out on top of a couple of low speed collisions. If he had ever been hit by someone going as fast as you he would never even consider risking a collision with you.
Always expect the other skier to do his/her best to collide with you.
We now return you to your regularly scheduled programming.
