As long as there's snow, Columbia Golf Course has tubes, sleds, cross country skis, and snowshoes for rent. Not for the faint of heart, Columbia boasts the steepest hill for miles around. Admission is free. But you've gotta sweat for the privilege of flying down this hill as many times as your heart desires. There's no tow line to haul you back up, so you have to make the industrious trek on your own the way your grandparents did it. The nearby Columbia Manor clubhouse is a warm place to thaw out, and serves cocoa on weekends.
