With the amount of snow we have on the ground here right now + the fresh we received in the last 2 day's, this snow is not going anywhere for a while. Present snow cover UP here in the Keweenaw is at 45". I would suspect they would extend the grooming with all that we have on the ground. Nonetheless, even if they did stop grooming, does not mean you can't ride here. Could be riding into late April...-Mezz
