I love how everyone comments everytime SKG makes a track, but almost never for anyone else.
Set near the California-Oregon border on the coast, the Pacific Coast Raceway is a sort of American NRing. Later modifications saw the addition of a modern arena front straight, a pair of short circuit layouts staying true to the original's style, and one very fast section of track on the southwest part being modernized because of the danger of the original layout.
7.8 mi./12.58 km (the front straight is a cause for discussion due to its length [bloody FIA])
