Teams played six or seven exhibition games. In 1966 (and 1960), the NFL had an odd number of franchises, so one team was idle each week. In 1978, the league changed the schedule to include sixteen regular season games and four exhibition games. From 1978 through 1989, the sixteen games were played over sixteen weeks.
At 5:36 p.m. on March 27, 1964, a 9.2-magnitude earthquake erupted 78 miles east of Anchorage, Alaska. The earthquake remains the most powerful earthquake to strike North America, and the second-largest earthquake ever measured.
Tehachapi is best known for the 7.3 1952 Kern County earthquake on the White Wolf Fault in 1952. At the time, the earthquake was the largest in Southern California in the twentieth century and the largest since the 1872 Lone Pine earthquake. It was felt as far away as Reno, Nevada.
