I just read that they're planning to plow the WOD this week. They said that their policy is to leave the trail unplowed for a while for xcountry skiers, then they plow down to 1 inch and let the rest melt.
That's great news. I thought the snow on the W&OD wouldn't fully melt until April at this rate. There are LOTS of fallen trees on the trail, so that'll be a challenge for the folks doing the plowing.
