During the past few winters I’ve been fortunate to introduce my teenage son to the joys of skiing. No film crew is needed to conjure a fake snowstorm on our arrival at the valley station to pick up our skis. Instead the real thing falls around us in heavy clumps, as we wrestle our unwilling feet into unwieldy ski boots. Back at the valley station we meet Johanna, our guide for the day. Back at the valley station I meet Mario Gruber, the managing director of the company that operates these cable cars.
