My nephews stumbled on a way to combine their two favorite hobbies: skiing and horseback riding. What they didn’t know is that this hybrid sport has a name. Skijoring is Norwegian for “ski driving” and has been around a while—although no one is sure how long. Variations include getting pulled by a dog (or more likely a team) or a machine. Competitions exist wherever snow is deep enough to hold them, including the championships in Whitefish, Montana.
