Someday, when you are an old, old man, you will look back on your life and think about all the dumb things you ever said or did in your lifetime. And when that day comes you will find that the above quote, from the 2004 season, is #1 on your "said" list.
I'm really glad you brought up racing and compared it to recreational skiing. Because racing is my life from mid March through October. Clearly this is a subject you know very little about. For example; noone goes BACKWARDS on a race track. In fact it is so plainly UNTHINKABLE that there is no reason to put it in our rules book:

(server is down right now but should be up by a.m.)
I would like to add that "riding uphill into oncoming traffic" is clearly not in the Skier's Responsibility code for two reasons: #1 it would comical to have such a statement in there and #2 until a decade ago it was "technically not really possible". So, here is a case where perhaps you should petition the committee that issues this code so that you can have an 11th code added: Though Shalt Not Shat On The Lord Thy Gods Warped-Space Anomalies.
Secondly, in racing the lead racer does have the right of way, as long as, the move is not "overly aggressive". On a more personal note (ie; use common sense) you don't do anything overly aggressive on a race track because the chances are great that even if you are 100% in the right you will still wind up sitting on the side of your track staring at your pale white femur bone and the big hole it made in your pants on the way out. So we purposely crowd out riders coming up on us (this is true) but it is done carefully in order to avoid personal pain and death. And "hooking a berm" and reversing direction on the track (and then citing the abscence of this rule in our official book) would definitely get you the horses ass award on race day. So the whole "racing analogy" thing is a red herring.
We still love you Jack and you are one hell of a bright guy. Big fan of your technical articles. Say, pulled a nice 360 myself this morning too. And I love the way it scares the pants right off the spodes when you come straight back up the hill right at them. And that's the best part of it for sure. On that I hope we can agree. Otherwise I exit this thread for good now. I don't really feel good beating up on such a great contributor to this site. But its just the internet. No big deal.
