(Undated) -- Measurable snow was reported in parts of southeastern and northern Minnesota this week and the DNR's Pat Arndt says trail conditions in those areas are looking good for winter enthusiasts. Arndt says Minnesota has over 22-thousand miles of groomed snowmobile trails that are groomed primarily by volunteers. The latest trail conditions can be found on the DNR's website. Arndt says they are updated after 2:00 p.m. every Thursday, just in time for the weekend.
