"The Worlds Fastest Half-Mile", Bristol Motor Speedway, located in Thunder Valley, Tennessee is one of the most popular tracks in NASCAR. This all-concrete construction is similar to Dover, except far shorter. The track is so short that speeds here are far lower than is typical on most NASCAR oval tracks, but very fast compared to other short tracks due to the high banking, making for a considerable amount of "swapping paint".The congestion inherent in this facility and the power of the cars has been likened to "flying fighter jets in a gymnasium".
