Do not wait too long into March. Here is what happens most years in the Hills. Winter sets in fast and the snow usually reaches its peak about this time of year. Riding is usually great until shortly after President's Day the end of Feb. After that time it is like someone throws a switch and the weather warms up and the sun really beats down hard. The majority of years sledding in the Hills is pretty much over by about the 10th of March. Trail grooming ends the 15th. Most years trail grooming gets a little sporatic after the first of March because the general weather pattern changes so much. Sure you will get some snowstorms in March but you better be there when it happens. No grooming and it is 60+ degrees afterward. March snows are very wet in the Hills. Bottom line is this. After the 1st of March conditions deteriorate rapidly and after the 15th I would not count on good sledding in the Hills. You have about 3-4 weeks left out there and then you are pretty much done.
