Keeping the trails closed to all motorized use EXCEPT for Snowmobiles to preserve the snow until May 1st... This is the first time I've heard of it. It has been extended to April 15th a few times in the past on good years like this. I'm glad to see it personally! We've got good snow down low and the trails are in top shape, seems a waste to have them go from great to destroyed in two weeks time.
