Racetracks are not merely ovals or circles. They aren't just corners and straight sections combined into a loop. Racetracks are highly engineered ribbons of pavement stringed together to provide a challenging circuit. The best racetracks in the world incorporate the natural contours of the land in their design. They are steeped in history, in triumph and failure, excitement and tragedy. As motorsport enthusiasts, we're naturally drawn to the appeal of circuit racing courses. Here are my top three favorite racetracks:[caption id="attachment_1569" align="alignleft" width="300" caption="Audi R8 at Homestead Miami Race Track"]
