The National Association for Stock Car Auto Racing. It is the fastest growing motorsport sanctioning body in the world, and has divisions in the US, Canada, Mexico, and now Europe. It is commonly used as the object of bigotry by many people, claiming only trashy southern people watch and compete in it and that the cars only make left turns. NASCAR competes on a wide variety of ovals and a handful of lengthy road courses in its top-two divisions, and the majority of incoming drivers that are hired into the Sprint Cup Series actually come from the north in this day and age. Contrary to popular belief, auto racing is very physically demanding,with a driver typically losing 10 pounds during a race. It also does require skill, and even road course racing veterans experience difficulties on ovals when they crossover to NASCAR.
