Lily Thomas lay in bed when the alarm went off on a snowy January morning in Squaw Valley. She opened her eyes for just an instant and saw the thick snow swirling beyond the windows of the house her father had rented, and for a fraction of an instant, she wanted to roll over and go back to sleep. She could hear the dynamite blasts in the distance to prevent avalanches, and just from a glance, she knew what kind of day it was. You could hardly see past the windows in the heavy blizzard, and she knew that if the mountain was open, it wouldn't be for long. But she loved the challenge of skiing in heavy snow. It would be a good workout, and she didn't want to miss a single day with one of her favorite instructors, Jason Yee.
