THE CHANGING SOUTH

Stock-car racing, a popular "good-old-boy" tradition, had a southern concentration until the late 1990's. This sport is still intensely associated with the South than any other region or country, even though its popularity has spread throughout the United States (Regional landscapes of the United States and Canada).

Los Angeles, the largest city in the state, hosted both the 1932[1] and 1984 Summer Olympics[2]. Squaw Valley, California hosted the 1960 Winter Olympics[3].
