He currently races on local dirt and asphalt tracks around the country while driving part-time in the NASCAR Camping World Truck Series and the ARCA Racing Series for his own Ken Schrader Racing.

Despite having a full-time NASCAR ride for over twenty years, Schrader frequently races at local tracks between NASCAR races. He races in many racing divisions, and has been successful in any division he has stepped into. He owns a dirt late model and dirt open wheel modified car. Both of these cars, along with his Camping World Truck Series and ARCA series cars, are sponsored by Federated Auto Parts. He owns I-55 Raceway in Pevely, Missouri, and is co-owner of Macon Speedway, near Macon, Illinois, along with Kenny Wallace, Tony Stewart, and local Promoter Bob Sargent.

John Harold Force (born May 4, 1949 in Bell Gardens, California) is an NHRA drag racer, a 15-time Funny Car champion driver, and a 17-time champion car owner. Force owns and drives for John Force Racing. He is one of the most dominant drag racers in the sport with 133 career victories. He graduated from Bell Gardens High School and briefly attended Cerritos Junior College to play football. He is the father of drag racers Ashley Force Hood, Brittany Force, and Courtney Force. His oldest daughter Adria Hight is the CFO of John Force Racing [JFR].

Current drivers racing under him are son-in-law Robert Hight and daughter Courtney. Mike Neff, who was once the crew chief for rival driver Gary Scelzi, raced in a 4th Funny Car for Team Force from October 26, 2007, following the death of Eric Medlen, until the end of the 2009 season. However, in 2010, after a '09 season in which John did not win a single race, Force parked his 4th car, and named Neff as his new crew chief instead. This decision resulted in Force winning his 15th NHRA Championship.

Doris Day (born Doris Mary Ann Kappelhoff, April 3, 1924) is an American actress, singer, and animal rights activist. With an entertainment career that spanned through almost 50 years, Day started her career as a big band singer in 1939, but only began to be noticed after her first hit recording, "Sentimental Journey", in 1945. After leaving the Les Brown & His Band of Renown to try a solo career, she started her long-lasting partnership with Columbia Records, which would remain her only recording label. The contract lasted from 1947 to 1967, and included more than 650 recordings, making Day one of the most popular and acclaimed singers of the 20th century. In 1948, after being persuaded by Sammy Cahn, Jule Styne and her agent at the time, Al Levy, she auditioned for Michael Curtiz, which led to her being cast in the female lead role in Romance on the High Seas.

With a legendary Hollywood "girl next door" image, and capable of delivering comedy and romance as well as heavy drama, she appeared in 39 films, released 29 albums, spent 460 weeks in the Top 40 charts and eventually became one of America's most beloved entertainers. She received an Academy Award nomination for her performance in Pillow Talk, won three Henrietta Awards (World Film Favorite), a Grammy Lifetime Achievement Award, Presidential Medal of Freedom, Legend Award from the Society of Singers, Los Angeles Film Critics Association's Career Achievement Award and, in 1989, received the Cecil B. DeMille Award for lifetime achievement in motion pictures.

Gregory Jack "Greg" Biffle (born December 23, 1969 in Vancouver, Washington) is a NASCAR driver who drives the #16 3M Ford Fusion for Roush Fenway Racing in the Sprint Cup Series. After racing in the NASCAR Winter Heat Series in the mid-90s, he was recommended to Jack Roush by former announcer Benny Parsons. He subsequently became champion in NASCAR's other two national touring divisions, the Nationwide Series and the Camping World Truck Series.

Biffle grew up in Camas, Washington and began his racing career driving on short tracks around the Pacific Northwest. He first gained national attention as a driver when he raced in the nationally televised Winter Heat Series in the winter of 1995–1996. Biffle dominated the series championship that winter, leading former ESPN announcer and NASCAR champion, Benny Parsons, to recommend the driver to Jack Roush.

Biffle entered the first two races of the 1996 Winston West Series, finishing 30th at Tucson and 4th at Altamont. His debut in one of NASCAR's national divisions came later that year when he ran the final two Busch Series races of the season. Driving a Chevrolet for Dick Bown, he finished 23rd at Rockingham but lost an engine the following race at Homestead and finished 36th.
