America has always been the most extreme country, from the Boston Tea Punchings to having the first man swear on the moon. We hold this shredding guitar solo to be self-evident with today's Groupon: for $18, you get two all-day passes (a $15 value each) to the ski-and-snowboard terrain park and $8 worth of snacks at the Hillside Dairy Bar at Ski Ward in Shrewsbury (a $38 total value). The terrain park is open to advanced skiers 8 years of age and older. Participants must provide their own equipment.

Ski Ward facilitates wintry whimsy under the summer sun with a terrain park built using Neveplast, a snow-like substance with none of snow's chilly properties. The park features a 16-foot box, two rails, and a picnic table, providing snowboarders and skiers with plenty of opportunities to perform tricks and compliment each other's sound fundamentals. The park recommends that participants don protective gear such as kneepads, helmets, and elbow pads, rather than the six layers of bubble wrap used by figure skaters. After an afternoon of summer snow sports, guests can refuel at Hillside Dairy Bar with the help of its fully stocked menu, which includes such delicacies as a large three-topping sundae ($5.50), lightly breaded chicken tenders ($6), and veggie burgers ($4.50).
