Pal Recording Studio (1957–1964) was an independent recording studio that operated in Cucamonga, California, an unincorporated community in San Bernardino County that later merged with the communities of Alta Loma, and Etiwanda to form Rancho Cucamonga. The studio was started by engineer/innovator Paul Buff. It was known for its instrumental Surf music recordings such as "Wipe Out" and the original demo recording of "Pipeline." It was located first at 8020 North Archibald Avenue and later moved a few doors down to 8040. Pal was also the training ground for a young Frank Zappa who worked at the studio starting in 1961. Zappa learned basic recording techniques at Pal. He recorded his first rock n' roll record, "Breaktime", by the Masters, which consisted of himself, Paul Buff, and Ronnie Williams. In 1964, Zappa bought the studio and renamed it Studio Z. Zappa lived at the studio building for a few months before it was closed in 1965. The building had to be torn down in order to widen North Archibald Avenue. Zappa made many other recordings at the studio. Some were released by small Los Angeles record companies, such as Original Sound. Other recordings were kept in his vault and released on albums such as Lumpy Gravy (1968), Mystery Disc (1985), The Lost Episodes (1996), Cucamonga (1998) and Joe's Xmasage (2005). Paul Buff engineered the original demo recording of "Pipeline" by the Chantays and "Wipe Out" by the Surfaris using his unique custom built recording machine, which recorded 5 tracks on 1/2 inch recording tape. Buff went on to invent the Kepex, an acronym for KEyable Program EXpander (the opposite of an audio compressor). Paul Buff's Allison Research studio processors became common on pop recordings (Alan Parsons would use a Kepexed drum sound to create the 'heartbeat' heard on Pink Floyd's The Dark Side of the Moon.) In 2012, Crossfire Productions (in partnership with Buff) released a five CD collection containing 156 of Buff's PAL recordings entitled 'Paul Buff Presents: Highlights From the Pal And Original Sound Studio Archives'. The collection featured 58 Zappa-involved recordings including an early version of Why Don't You Do Me Right? (which later appeared in 1967 as the A-side of a Mothers Of Invention single) and the previously unreleased Zappa novelty song, "Masked Grandma". Other notable musicians/bands that recorded at Pal Recording Studio: The Tornadoes Dino Dupree and the Pharaohs Conrad and the Hurricane Strings Notable songs: "Wipe Out" - The Surfaris "Pipeline" - The Chantays (Demo) "Tijuana Surf" - The Hollywood Persuaders (a Zappa production) "Grunion Run" - The Hollywood Persuaders (another Zappa production, which was a hit record in Mexico)

Ontario Motor Speedway was a motorsport venue located in Ontario, California. It was the first and only automobile racing facility built to accommodate major races sanctioned by all of the four dominant racing sanctioning bodies: USAC (and now IndyCar Series) for open-wheel oval car races; NASCAR for a 500-mile (800 km) oval stock car races; NHRA for drag races; and FIA for Formula One road course races. Additionally, several motorcycle races were held at the track. Constructed in less than two years, the track opened in August 1970 and was considered state of the art at the time.The first full year of racing included the Indy-style open wheel Inaugural California 500 on September 6, 1970; the Miller High Life 500 stock car race on February 28, 1971, the NHRA Super Nationals drag race on November 21, 1970 and the Questor Grand Prix on March 28, 1971. Each of these inaugural races drew attendance second only to their established counterparts, the USAC Indianapolis 500, the NASCAR Daytona 500, the NHRA U.S. Nationals, and the U.S. Formula One race at Watkins Glen. The track was purchased for real estate development by Chevron Land Company in late 1980 and demolished at a cost of $3 million in 1981. It is estimated that the 800-acre (3.2 km2) facility, with 155,000 permanent seats and an air-conditioned private stadium club would have a replacement cost in 2009 of over $350 million.
