This topic is a tired, dead horse that barely warrants our attention. Nevertheless, newcomers seem to want to vent about snowboarders and rude people on the hill.
Although I never hit anyone during my days as a punk youngster, I certainly p@ssed a few off. No one ever tried to fight me, got in my face, or called me a faggot. What they did was explain in a civil manner what I was doing wrong (sitting in an unsafe place), why it was wrong, and the possible consequences of my actions. The people explaining this were usually seasoned vets of the slopes...you could tell by their gear, clothing, and attitudes.
Nothing reinforces good slope etiquette more than a civil explanation from an "insider." Whenever I'm in uniform and see snowboarders sitting in unsafe spots, I take a second to let them know. I don't yell, I don't swear, I don't berate (even if I almost killed them). Just say, "Hey guys, you can't be seen from above, try to stop on the side of the trail where it's a bit safer."
Every so often I'll throw in a, "Ya know, these damn old fart skiers are becoming more and more crotchety in their old age...you don't need an assault charge on your record b/c some vigilante idiot tried to start with you or called you a faggot." They straighten up immediately. Everytime.
