The season of winter sports is now in full swing. Today, as compared with a generation ago, there is an entirely different meaning to winter sports. Yesterday it meant skating and tobogganing mostly; today it means largely attendance at various indoor sports. Our remarks must, necessarily, pertain to the thickly populated centers of the North and East sections of the United States. In days of not so long ago, the winter months with sub-freezing temperatures brought us an opportunity to disport ourselves out-of-doors on ice and snow bound river, lake, and hillside.
