 Some host cities are heating up the challenge even more. In Montana, skiers race through fire as the snow flies. This is not for the faint of heart. Any injuries over the years? I've had a few. I've had a broken nose. I've had a few concussions here and there. I landed on top of a minivan one time. They call it skijoring. Skijoring started in Nordic countries with reindeer as a way to get around.
