The pedal pioneers at Boschertown Grand Go-Karts have been facilitating high-speed adventures on one of the largest tracks in the Midwest since 1957. 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.
