The groomer went to the top of Merrimac today and then to the dam. They plan to head to Big Creek tomorrow. There are very big holes (up to 10 feet) in the gutters along the trail . These gutters tens to be covered with a thin layer of snow. They are so big that they can swallow snowmobiles. A rider fell in one yesterday and had to be taken to Quincy Hospital. BE CAREFUL. lj
