Modern go-karts are a spinoff of supermarkets' traditional motorized carts, whose ferocious speed led to high-stakes races to the sales racks and messy wrecks in the produce section. Zip around a more ideal racing environment with today's Groupon: for $39, you get two kart-racing passes at Motorsports Country Club of Cincinnati in Batavia (an $85 value). Each pass is good for one 15 minute ride.

Motorsports Country Club straps mini-car enthusiasts into speedy Sodi and Rimo karts to help them realize their apex-hitting dreams at up to 40 m.p.h. Before any rubber is burned, trained instructors fill drivers' heads with tips on track etiquette and safety, ensuring the good advice can't escape by fitting noggins with a rented helmet. Then, riders set out to pursue a healthy, windblown look by speeding around the 0.7-mile-track's 15 turns, which can be arranged in six different layouts to challenge both novice and veteran kart racers. Spectators can observe the action in comfort from the visitor's viewing area or visit the club house to view gear dedicated to the fine art of kart racing. Although closed on Mondays, Motorsports is open Tuesday–Friday from 3 p.m. to 8 p.m. and Saturday and Sunday from 12 p.m. to 5 p.m.
