Snowboarding doesn't have the counterculture/rebel vibe any more. I've heard teenagers say they switched to skiing to try something different. So now I guess snowboarding and skiing are competing on an equal basis. Which means among other things, you have the difference in learning curve between the two. Most everyone agrees that skiing is easier to learn (at the beginning) than snowboarding, so I guess a drop in new boarders is inevitable.
In retrospect, "Let's get the goat drunk"
should have been my cue to leave the party.
