Northern Michigan is working hard on bringing more of the silent sports to the area. The latest news is there are some new sled dog racing events in the pipeline.

The wonderful little town of Steamboat Springs is the western capital of skijoring; there is not a skijoring capital in the eastern U.S., which town in northern Michigan will embrace the title?
