WINTERSPORTS -- Kootenai County Snow Groomers and Sheriff’s Office Backcountry deputies have announced they will be installing barricades at National Forest trailheads today so trail grooming can begin tomorrow, Dec. 22.

Following are details from the Kootenai County Sheriff's office:

Once the barricades are in place, only snowmobiles and authorized off-highway vehicles will be allowed onto the trails. Additionally, users of the groomed trails must purchase and display the current year’s registration and Groomer’s Sticker. Violations of this ordinance constitute a misdemeanor.

An authorized off-highway vehicle (OHV) is an all-terrain ATV, motorcycle, or utility type vehicle (UTV), under two-thousand pounds, with a maximum width less than seventy-four inches, which is designed for travel on snow or ice over natural terrain and is steered by tracks, skis or runners.

Trail users are cautioned not to pass a groomer on a trail in either direction, instead wait for the groomer operator to see you and they will stop and let you by in a safe place.
