I don't drink. I don't hang out late in the mountains--I would rather rest, tune/wax/repair my skis, watch ski instruction videos, etc. and save energy for the next day. I make enough money for decent living but hate paying resort prices at restaurants and thus make focused efforts to stay/eat thrifty/healthy. None of my friends are hardcore like me, so I'm used to skiing alone and at my own pace. Nor do I want to slow down others. OTOH, I'd love to find like-kind ski buddies for safety and to help each other out when needed. I'd really like to become effective and proficient in skiing moguls this year.
Would one-track minded obsessive loner skiers like me find these gatherings worthwhile? I guess I would never really know until I participate in one.
I don't drink alcohol either. I'm over 55 and don't have much energy for socializing after a full day of skiing. I organize a VRBO house full of friends so that we can cook and eat in at least a few times during a ski week. Sometimes I ski with a friend or two, sometimes I go off on my own for a few hours. Same applies to a Gathering. Sometimes I ski with one of the groups, sometimes I ski with 1-2 of my friends, sometimes I ski alone. Do I need to attend a Gathering? Not really. Have I attended a Gathering before? Yes, at Bridger/Big Sky. Do I think that I and my friends will have fun skiing with others equally obsessed with skiing and learning from folks with local knowledge about the Aspen mountains? Definitely yes!
