Destiny Nash stands in a swirl of white smoke as a pile of dust gathers at her feet. The 18-year-old is sanding a car bumper, part of her auto-collision class at Palmetto Academy of Learning Motorsports. The class is part of a unique curriculum being offered at the Horry County charter school, making it the only motorsports high school in the country. While there are other high schools in the U.S. that offer a racing program, the Conway school, located at 826 W. Cox Ferry Road, Conway, SC, is the only one that provides a hybrid learning curriculum.
