Here's my favorite quote from the article...
"One reason may be that snowboarding simply doesn’t have the rebel cachet that it once did. Skiing has appropriated everything from snowboarding’s swagger to its trendy clothing to technology like fat skis. Simply put, it’s cool to be on two planks again."
Oh god no. No it isn't. Like rollerblades vs. skateboards this recent surge of young kids wanting to ski instead of board will soon pass.
I think there's something in this. Snowboarding is great - especially in powder - but let's be honest here, you can do everything on skis now too (probably more, and faster). In Europe, at least, snowboarding is no longer "cooler" than skiing.
I know a few very good multi-discipline folk who have opted for skis and only really bring their boards out for heavy powder surf days. They insist skis are just easier and more flexible.
