Our grooming is limited by the weather as well as the funding level we receive from Washington State Parks and Washington Recreation & Conservation Office. Ultimately, the funding for grooming comes directly from the registration of snowmobiles and can vary from year to year based on the number of registrations purchased. If you would like to contribute funds to help with grooming, please send it to MTGA, PO Box 224, Winthrop, WA 98862.
