The inner tube's snow-sliding abilities have proven more enjoyable than wintry recreation via sled-mounted bicycles and snowshoeing horses. Saddle up for frictionless fun with today's Groupon: for $15, you get two admission tickets for two hours of snow tubing at Timber Ridge in Gobles (a $30 value).

Timber Ridge caters to winter recreation enthusiasts of all ages and skill levels, boasting sleddable slopes perfect for a variety of low-friction conveyances. Hit the specially reserved tubing lanes for two hours of sliding, coasting on downhilling donuts from a lofty hilltop perch to a naturally powdery landing platform beneath. During the speedy jaunt down the inclined plane, riders can clutch the handles conveniently affixed to their tube to evade snow banks or avoid holding hands with clingy snowmen. Post-plunge, tubers can retire to Timber Ridge's lodge, which offers concessions, picnic areas, and more to refuel and defrost. Check the snow report and tubing hours before heading to the slopes.
