Honestly, I see the question kind of in reverse. If I had to move farther away from skiing for my job, how would that impact my skiing? If I couldn't afford or chose not to pay for a condo in the mountains, how often would I ski?

I think we all adapt to the situation we have. So right now, I would say, I wouldn't want to have a nighttime commute of more than 2 hours (typical case), and I wouldn't want to have to drive more than 10-15 minutes. But who knows what I'd really tolerate? And push come to shove, maybe I'd even ski less often. (Heresy!)
