Very interesting post. While there are a lot of similarities (time commitment, for example), I think one thing may be overlooked, and that's the change in technology. Obviously for golf, technology has changed dramatically, but it's still a difficult game, especially for the novice. Skiing, however, experienced a bit of a sea change virtually overnight with the introduction of parabolic skis. I'm not sure what the experts have said about this, but my opinion here is mostly shaped by own experience.
I've been skiing only a handful of times in my life. The first couple time was when I was in college at the base of the San Bernardino mountains. This was probably in 1993-1994. We drove up to the local mountains, and while it was fun, I found it very difficult to pick up. I could make my way down larger runs, but I was pretty much a snow plower. I didn't ski again until a few years ago. I work for a small consulting firm, and our CEO has a house on Deer Valley in Park City, Utah (which also happens to be one of the few resorts that does not allow snow-boarding). It's ski-in, ski-out. For the last three years, 10-11 guys from the office have gone out and skied for a few days. I was apprehensive at first, based on my initial experiences, and wasn't sure I'd even be able to make it down the mountain from the house. But the skis were just light years different in my opinion. Having gone 15 years without skiing, and poor skiing at that, I felt almost right away like I was doing what I was supposed to be doing. I could carry speed, carve parallel turns, and it was a really enjoyable experience. On our trips, there are guys who go out there to party and do a little bit of skiing, and guys who go to ski and do a little bit of partying. I'm definitely in the latter group, and am usually the last one of our group off the mountain (the great thing about ski-in, ski-out is that you're on your own schedule).
While golf technology has changed a ton over the years, I'm not sure there was ever a single change that was this dramatic. It would be as if we went from Hickories and Featheries to Titanium and Pro-Vs overnight. I'm not sure how much the change in technology has impacted the business, but skiing is definitely more enjoyable now than it was 15-20 years ago. If only it wasn't so damn hard to get your boots on and off.
