Roller skates are among the only survivors of the post-Model-T spree of wheeled inventions, outlasting the famed roller bathtub and the forgotten roller waffle iron. Celebrate enduring wheeled innovation with today's Groupon: for $8, you get admission and quad-skate rental for two at Big Wheel Roller Skating Center in East Stroudsburg (up to an $18.50 value).

At Big Wheel Roller Skating Center, skaters have exercised, peacefully slow-skated, and spun around with friends and family members in a wide, air-conditioned rink for more than 30 years. Although pant styles have rotated from bell-bottomed to skinny, quad skates have remained the same—four wheels arranged in a rectangle, with a rubber brake and a signature ankle-hugging turtleneck. Big Wheel's rink hours accommodate weekend date nights, family fun time on Friday evenings, and early-morning sessions for pre-work nostalgia. Poconos Discothèque on Wheels infuses skate sessions with a high-energy soundtrack that fuels sprint-skating, twirling, or high-stakes hokey-pokey competitions. Although not included in this Groupon, skaters can also forage at the snack bar or take a break in the arcade.
