Amy Brennan (Norway) sent in this follow up to Kim Klingaman's suggestion for the sport of skijoring. Here is an article titled, "Skijorers Aren't Just Horsing Around." She says, "Here's a story about the sport of skijoring, also referred to as 'water skiing on snow.' It was a Winter Olympic demonstration in the 1920s and some enthusiasts are trying to bring it back in style. They have all those equestrian events in the Summer Olympics, why not Winter too?"
