Location
City insight: Cool
Cool, formerly known as Cave Valley, is a small town in El Dorado County, California, about 40 miles (64 km) from the state capital, Sacramento. It sits at an elevation of 1,532 feet (467 m). The climate is Mediterranean, with hot, dry summers and cool, wet winters, so spring and autumn offer the most comfortable racing conditions.
