Though man's invention of the wheel was a triumph of engineering, it was the invention of the ice skate that finally enabled him to catch prey using only a triple salchow and a skillfully flung gold medal. Honor history's ice advances with today's Groupon: for $150, you get a pass for unlimited skating and skate rental. Choose between a 90-day pass for an individual, or a 30-day pass for a family of up to five at Woodland Hills Ice (a $300 value).

Woodland Hills Ice nestles 7,000 square feet of skateable turf amid lofty pine trees and fresh winter air. Families of up to five strap on complimentary skates and maneuver across the glassy rink, carving zigzags through the ice as majestic clouds lounge overhead to cheer on perfectly executed axels. The center is open all week long, and extends its hours late into the night, allowing skaters to spin in the sunshine or clench the railings beneath a bounty of twinkling stars any day they please.
