Snow has two positive uses: it can be used to build snow-jurors when neighbors don't show up to serve in a non-binding apartment court, and you can ski on it. Put precipitation to good use with today's Groupon for Ski Campgaw in Mahwah. Choose from three options:

• For $17, you get an all-day lift ticket (up to a $34 value).
• For $32, you get an hour-long group ski lesson, equipment rental, and a lift ticket (a $65 value).
• For $37, you get an hour-long group snowboarding lesson, equipment rental, and a lift ticket (a $74 value).

Aspiring snow-surfers can choose one of the latter deals to learn about skiing or snowboarding survival during a 60-minute group lesson, lead by one of Ski Campgaw's highly experienced staff. Afterwards, newly trained students show off their new moves in the beginner's area, where two gentle conveyor lifts can tow them back to the top of the slope. Meanwhile, more advanced skiers can challenge themselves on black diamond slopes, difficult for its steep angles and pursuing suitcase salesmen on jetpacks, while brave boarders can navigate the ramps, rails, and half pipes of the freestyle Terrain Park.
