Every time I think I'm out, they suck me back in............When you think about it there is no other explanation other then prejudice and discrimination that holds water.
Drifter, I know you wanted to do more than scratch the surface when you started this thread. Like you said, none of us knows the motivation for sure (although riverc0il has a better feel than we do)......but I can come up with several other reasons why the ban stays in place, and I think they are better than prejudice against the slac..........um, snowbaorders.
I'm more inclined to lead toward preservation. Of the culture (replacing the single with a single is kind of indicative of this kind of thinking). Of snow/trail conditions.
Let me speculate on why prejudice is probably a minor factor, if any, among MRG shareholders. Take riverc0il for example. I've seen him around the internets. Here, the Time for Tuckerman boards. The type of skier and backcountry enthusiast committed enough to put up his $$$ in a skiing coop. I suspect you don't find many who frequent Tuckermans who hold the prejudice you speak of. MRG is a skiers ski area (not that other aren't) but here a little moreso than other places. The vibe is nature as nature intended it, skiing as the mountain brings it to you without much interference from the corporate office. Respect for outdoor pursuits is probably high on the list when it comes to MRG skiers and owners (again, not that the same can't be said about lots of skiers at other mountains). These generally aren't the type of people who would shun other skilled outdoor enthusiasts just because they ride a board instead of two planks. So, for me, it's the prejudice angle that doesn't hold H2O.
Is is any coinkedink that Alta, another throwback resort in attitude/culture and serious skiers mountain, is another of the offending snowboard banners? I don't think so, and I bet many of the MRG skiers/owners and Alta regulars would prolly get along real well.
So, I would finish 'MRG bans snowboarders becsuse..............' with they strive to preserve the best skiing conditions for their shareholders and skiers, while maintaining a culture and atmosphere with which they most identify. MRG owners are skiers, not that they have anything particular against snowboarders other than the fact that they way they impact conditions on the hill can be detrimental to ski conditions.
