Kart racing, like alligator wrestling, requires steely nerves, fast reflexes, and tranquilizing darts to get ahead. Wrangle a racetrack with today's Groupon: for $20, you get two 20-lap kart races at Grand Prix Raceway in Lakewood (a $40 value).

At Grand Prix Raceway, Italian racing karts equipped with 200cc Robin/Subaru engines scream around a quarter-mile racetrack at up to 35 miles per hour. Drivers receive basic vehicle instruction, a kart and helmet, and a head sock before slipping into the seat of their little buggy. Computerized timing and scoring eliminates fights over who finished first, and a monitor blares notifications of when a driver obliterates a racetrack record. Fans can roar and cheer from a climate-controlled viewing room, and a barrier system and referee keep races safe and assuage worried sedans wringing their tires in the parking lot.
