The groomers are asking everyone to stay off the trails all day on Monday, to avoid making ruts that will then freeze solid. In particular, please do not go out in the evening after the rain stops. The trails will still be soft. And don’t think that if you’re just one person, it won’t make a difference. It will. One person went skiing during the last thaw, and the ruts they left added hours to the time that the groomers had to spend to get the trails back in shape.
