Hike Up! Modern Dog Sledding

I'm standing in a snow-filled clearing in central Washington watching as one dog's bark becomes a fervor, spreading until 20 plus dogs are howling, whining and tugging on leashes, clawing excitedly at the snow. Across the clearing two sleds are anchored – eight dogs are harnessed to one, seven to the other – and each time someone begins to walk toward a sled, the howling grows louder and more frenetic. Today we're going dog sledding and it's very, very clear the teams are just itching to run.
