The first go-kart-racing track was a circle because it was designed to teach children how centripetal force feels without rolling them down hills in tires. Learn circularly with this Groupon.

Boschertown Grand Prix Racing
The pedal pioneers at Boschertown Grand Prix Racing have been facilitating high-speed adventures on one of the largest tracks in the Midwest for more than half a century. In the early days of racing, the course served as a venue for the homemade karts of avid individuals, but now houses a herd of go-karts, sprint-karts, and super-karts that eliminate the possibility of unfair home upgrades such as engines outfitted with nitrous or the flux-capacitor of a 1981 DeLorean. Drivers as young as 10 reach speeds of up to 17 mph in a standard kart; racers 16 or older helm 24 mph sprint-karts; and drivers 18 or older take control of 28 mph super-karts. Wheels roll over hairpin turns, banked corners, straightaways, and opponents' rights to call themselves "Greased Lightning" as drivers dominate laps around the 5/8-mile track.
