SCOTTSDALE, AZ—Driving up the narrow student-only entrance ramp and plowing over speed bumps as if they were sand dunes, Robert T. Everett High's Class of 2012 thundered through their school's parking lot Monday like the coalition forces storming Baghdad. "You ready to rock, Big Ace?" said 17-year-old senior Brian Grady, removing his sunglasses as he addressed an Aéropostale-shirt-wearing Curtis Jenner, who nodded his head while hanging out the sunroof of a Hyundai Tucson as if it were an armored M1151 Humvee blasting "Welcome To The Jungle" into the arid desert air. "Let's do this, Double Dutch." At press time, the 117-strong force had sprung from their vehicles and breached the school's hallways on foot, equipped with their Jansport backpacks, lunch money, and a surge of adrenaline pounding through their veins.
