RPM Indoor Kart Racing, Sacramento

RPM Indoor Kart Racing indulges a driver's need for speed with two connectable indoor racecourses, refereed by staff members during high-octane heats. After stepping into the spacious lobby with high ceilings and a two-story window overlooking the track, adult drivers slap down a valid driver's license and sign a liability form in exchange for a racing suit and helmet. Once suited up, they climb into a 9-horsepower race kart that reaches speeds of up to 40 miles per hour, roughly the speed of an ostrich riding a moped.

The raceway's two sweeping thoroughfares—the Monster Energy Track and the Unbound Energy Track—send amateur IndyCar drivers zooming around adrenaline-filled turns. On Mondays, the two courses unfurl into one gargantuan raceway—the Lost Big Gun Track. Races include sprint and grand prix competitions with 8–10 racers, or Hot Laps that pit drivers against the clock, which despite one hand being smaller than the other, is actually a pretty good driver.

Guaranteeing maximum safety, referees keep their eagle eyes peeled during every race to enforce the courses' rules of the road. After heated competitions, former enemies bury the hatchet and become lifelong frenemies over refreshments in the Skybox, a windowed lounge that overlooks the tracks.
