Reverse skiing up a mountain is only possible during full moons on the summer equinox, which is why Rube Goldberg invented ski lifts. Enjoy newfangled altitudinal fun with today's Groupon: for $21, you get a nine-hour lift ticket at Labrador Mountain (a $45 value).

Voted the Best Place to Ski in the Syracuse New Times, Labrador Mountain boasts 22 trails, ranging from the beginner's Char Run trail to the expert Cut Throat, 14 of which are brilliantly lit for twilight tootsie sleigh rides. The mountain's sprawling 250 acres play host to a ski shop, a children's center, and a slew of dining facilities. Just 30 minutes outside of Syracuse, Labrador Mountain keeps its powder open to the public from December to April, and offers lessons for both kids and adults during the daytime hours.
