Something as benign as flat light can make a slope look different. Throw some heavy snowfall and wind gusts into the mix, and you'll hardly recognize the place. Fair-weather skiers are only equipped to enjoy the snow that comes with fair weather. Skiing on the ugly, stormy days will not only desensitize you to the physical discomfort, it'll prepare you for tricky and sometimes scary conditions. If you want to enjoy the spoils, you have to successfully weather the storm.
