Several years ago a group of members from Western State Vintage Snowmobile Clubs
started getting together to hold informal racing events. They organized single-cylinder
vintage snowmobile races; more commonly known as “one-lunger racing’.In 2007 an informal association became known as Track-N-Trail 1 Lunger Snowmobiles.
The events are not for professional racing, but a group of vintage snowmobile enthusiast
just out for a day of fun. Anyone can participate.Contact:
