Any mountain dweller will confirm that happiness comes in many forms, and especially in the form of snow. Happiness squeaks beneath your snowshoes or whispers in your ear as you ride on a dog sled. It brushes your face during a snowball fight. Your fingers touch it as you build a funny snowman. When you ride the rail toboggan, hurtle down a slalom slope or pedal a fatbike across the snow, you may think you’ve left it behind. But it will always catch up with you.
