Go-karts can help teach children the fundamental rules of the road: Its banked tracks reenact dangerous cul-de-sacs, and its rules remind of the importance of wearing a helmet while driving. Conduct your own crash course with today’s Groupon: for $15, you get four go-kart tickets, 10 batting-cage tokens, and 20 arcade tokens at Selden Batting & Grand Prix, located a mile east of Nichols Road Route 25 (a $39 value).

Selden Batting & Grand Prix satisfies the competitive appetites of fun-starved families with a wide variety of outdoor attractions. The Grand Prix racecourse invites pedal-pushers to test their slaloming skills behind the wheel of one of three gas-powered go-karts, each equipped with safety harnesses to keep competitors strapped into their unencumbered carriages. Rookie carts allow juvenile drivers (50 in. and taller) a chance to rule the road, and the double-seaters leave room for a hitchhiking instructor ($6 per ticket value, all go-karts). Mirth-seekers can also fine tune swinging skills with baseball and softball batting cages, where machines lob practice balls of varying speeds and orbits ($1 per token value, 10 swings per token).

Selden’s arcade assembles a cross-section of computerized competition and old-fashioned favorites. Engage hand-eye-leg-solar plexus coordination with virtual festivities such as Dance Dance Revolution, air hockey, and basketball, and then exchange your high scores for prizes ($0.25 per token value). Or, feel free to take a seat at the shady picnic pavilion and entertain taste buds instead by sampling from a spread of homemade ice-cream flavors or one of the 85+ different flavors of italian ice, including spumoni crème, cherry, and rainbow.
