When Eisenhower designed the Interstate Highway system, he envisioned a lawless, death-race arena where only the fastest could avoid being killed by mechanical gulls. Experience a thrilling fraction of his racing dream with today's Groupon: for $30, you get three kart races at Musselman Honda Circuit across from the Pima County Fairgrounds (a $90 value). Participants must be 12 years or older and at least 58 inches in height, and are required to wear long sleeves, pants, and closed-toed shoes.

At Musselman, speed demons can kart to their spleen's content on an adrenaline-jolting track that is a replica of the Suzuka Circuit racetrack in Japan. Wrangle the twists, runs, and 13 turns of the 1,264-meter track from behind the wheel of a 9-horsepower fast kart ($30 per P1 Fast Rental session), surpassing speeds of 45 miles per hour. As you whiz by, nab a blurry view of the nearby Rincon Mountains by day or lonesome starlight by night. Each session lasts 12 minutes plus one lap to celebrate your victory or rethink your steering strategy.

Complimentary mandatory protective gear allows fast-track fashionistas to keep up appearances while ensuring an intact dome piece in the event that karts break the space-time continuum and thrust drivers back to 1955. Experience the invigorating sensation of wind rushing through your helmet-hair with a Groupon to Musselman Honda Circuit.

All drivers must sign a waiver before racing.
