Pebbles constantly skip and bounce along the pavement surrounding Speed Park Motorsports, stirred from their inert rest by the constant thrum of engines. Go-karts grapple with sharp turns and lean straightaways on three tracks known as the Sprint Indy Style, the 1,200-foot Grand Prix, and the elliptical Thundermania course; while Statos Karts -- racing vehicles capable of speeds up to 45 miles per hour -- zoom around on Thundermania course. In Nitro Alley, real dragsters with amateur drivers explode from 0 to 75 miles per hour over 200 feet. Inside the venue, the simulated sounds of engines drown out the real thing in the 7,000-square-foot classic arcade. In addition to walk-in fun, the staff also arranges and hosts birthday parties and large groups for speed lovers of all ages.
