NASCAR-Discuss a scene

      It is known to all people that NASCAR'S racetracks are ovals. But most people do not known that all racetracks are different. Every racetrack's banking( upward slope at the end of each turn that allow driver to go faster on turns) has a different angle degree, so drivers have know what turn and lap they are on. This is why so many NASCAR drivers do this, its exciting for them in a way.As people may thinks NASCAR driving is easy and that's why many crashes happen at events.
