For one week each winter, the small town of Joseph swells to host mushers and spectators for Oregon’s Iditarod qualifier sled ...

These high energy dogs were bred for pulling sleds and require intense exercise and attention to prevent destructive behavior ...

Dog sledding is technically a competitive sport, but as an Idaho musher noted, for most, it's hardly a money-making business.

I’m not sure who’s having more fun, musher Michael Tarver or his sled dogs as we charge on through the white wonderland.
