Like learning to use chopsticks, skateboarding takes patience, dedication, and a particularly dexterous set of toes. Show off how flexible your feet are with today's Groupon: for $8, you get two unlimited-time admissions (up to a $16 value) to Inner Space Skatepark in Wallingford.

Designed by boarders, Inner Space Skatepark's 7,000-square-foot indoor skate park is a safe sanctuary where skaters can practice kickflips, develop aerials, or break in a brand-new deck. With a pair of unlimited-time passes, skaters can borrow a helmet ($3) and a board ($5) or bring along their own gear, then hit the ramps and handrails and test the limits of grip tape. Inner Space is open seven days a week, so neither rain nor pesky sunshine can stand in the way of a proper day gleaming the cube. Skaters younger than 18 years are required to protect their underage heads with a helmet, but those 18 and older just need to wear a full set of clothes.
