Fish, do you work with those folks coming up to the mountain for the first time? 'Where' is huge. The drive up to Crystal Mtn or Stevens Pass is fraught, and the trip is early. Mix in a couple kids, the dog, the cost of rentals for the family, the waiting, and the new and alien culture of the sport are daunting. It takes desire and commitment to take part even before the first ski lesson line up. I don't know that my family would have participated when we started in 1966 in similar circumstances.
In contrast, we had two small local hills minutes from town; five to the west and ten to the east. It was relatively cheap, and the town had a great ski club, gear swap, etc... it was easy to go skiing. Magic happened on those two small hills. 50+ years later, it still does. Small kids, go up for a couple hours and head home. Drop off the kids to ski after school. Hang out with the neighbors. Sure, the big areas have the vertical, the drama, the gnar, but the little hills have a high return rate and are the seed of the core skiing diaspora that keep the majors and indeed, the industry in business.. Phil, Trish, Kneale Bronson, and many others here share similar trajectories.
Back to the Seattle areas, we're seeing a ground swell of new skiers from non-skiing cultural backgrounds. Many locals now speak Mandarin or Hindi, and they don't quit. They want to ski. They're bringing the same energy and excitement levels to the sport that remind many of the late 60's and early 70's. Skier days are NOT down in this region with the exception of the occasional low snow winters. Parking lots are full by 9:00am. Local shops sell through their rentals by Christmas in many cases, and sell through rates at local retailers is very good.
The only thing that could derail this is a significant downturn in the economy, which is always possible, or radical changes in immigration laws. Skiing is expensive, period. I'm rambling a bit now and absolutely recognise that all is not always bright and well in the winter sports world. There's more competition from other activities for families drawn to sport. Ski culture itself is atomized into subcultures that aren't welcoming to newcomers, and in the end, for most adult learners, skiing isn't easy.
Sure, one can become a competent intermediate, but that may still take several seasons of 8-10 days a year participation. Many can't and won't do it. One trip is a lark, but many just don't have time and energy after putting in a 50+ hour work week, and that's before we talk about stagnant wages in work fields that previously could have supported a family and a ski habit.
Anyhow... all is not as bleak as you suggest, Fishbowl. Statements that 'they had a miserable time so they didn't come back' seems more a hyperbolic extrapolation of opinion from the figures presented that certainty isn't shared by all or even many here from what I can see, but anyhow, that's enough for now.... and we're on page 6.
