Some context: The Merchandise Mart (or the Merch Mart, or the Mart) is a commercial building located in the downtown Loop, of Chicago, Illinois, United States. When it opened in 1930, it was the largest building in the world, with 4,000,000 square feet (372,000 m2) of floor space. The art deco landmark is located at the junction of the Chicago River's branches. The building is a leading retailing and wholesale destination, hosting 20,000 visitors and tenants per day as of the late 2000s.
Wholesale showrooms occupy 50% of the usable floor space, and the Sultan of Brunei once spent $1.6 million at the Mart to furnish his entire palace, claiming the location was the only place where the task could be completed in one week. Select showrooms are open only to wholesalers, with others accessible to the general public. Unlike stores with traditional shelf and rack displays, entire usable rooms are created, providing consumers an opportunity to compare form and function between applications and manufacturers. A portion of the stores offer items for purchase singly or as a collection, while others offer design services, preservation, renovation, or installation. In addition to being a resource for architects and decorators, the Mart also has featured award-winning designs as selected by the American Institute of Architects. Catering to suppliers, on-site firms specialize in providing professional services for market research projects.  In 1931, Marshall Field and Company lost five million dollars, followed by eight million in 1932. The wholesale division was greatly reduced and Field's reduced its space in the Mart from four floors to one and half. The Mart continued to display the latest trends in home furnishings within the showrooms and trade shows. The company recovered late in the decade, but did not return to all previously occupied space.  In 1942, L. L. Skaggs formed a partnership with three other men and named the partnership the Owners Service Company, hence Osco. The headquarters moved from Waterloo, Iowa, to the Merchandise Mart.  A retail shopping area, named The Shops at the Mart, opened in 1991 and includes apparel shops, beauty services, bookstores and newsstands, financial services, telecommunication services, travel services, specialty food and wine stores, photo services, a dry cleaner, shoe shine stand, and a food court. A U.S. Post Office is located on the first floor and a FedEx location is on the second floor.  The Apparel Center houses the 521-room Holiday Inn Chicago Mart Plaza River North hotel, the offices of the Chicago Sun-Times and the Chicago campus of the Illinois Institute of Art - Chicago, as well as the Chicago office of the Ogilvy & Mather advertising agency. GoHealth occupies 93,000 square feet (8,600 m2) on the 5th floor of Merchandise Mart, the Potbelly Sandwich Works' corporate offices are located in the tower. Motorola Mobility moved its headquarters to the Merchandise Mart in 2014.

Some context: Kulwicki grew up in Greenfield, Wisconsin, a suburb of Milwaukee known for its Polish-American neighborhoods, near the Milwaukee Mile racetrack. After his mother died, his family moved in with his grandmother, who died when Kulwicki was in seventh grade. A year later, his only brother died of a hemophilia-related illness. Kulwicki attended Pius XI High School, a Roman Catholic high school in Milwaukee, and received a bachelor of science degree in mechanical engineering from the University of Wisconsin-Milwaukee in 1977.
Kulwicki began his racing career as a 13-year-old kart racer. His father built engines as the crew chief for Norm Nelson and Roger McCluskey's United States Automobile Club (USAC) racecars. Because his work involved travel, Kulwicki's father was unable to help his son at most kart races, so Kulwicki's resourcefulness was often tested trying to find someone to transport his kart to the track. Even when Kulwicki asked his father for advice, he typically ended up doing most of the work himself. "I showed him how", Gerry Kulwicki said. "And he said: 'Why don't you do it? You can do it better.' And I said, 'Well, if you do it for a while, you can do it better.'"  Many local-level American racetracks host their own season championships. In Wisconsin, numerous locations held dirt and asphalt short track racing. Kulwicki started driving stock cars at the local level at the Hales Corners Speedway and Cedarburg Speedway dirt oval tracks. In 1973, he won the rookie of the year award at Hales Corners Speedway in the Milwaukee suburb of Franklin, and the next year started racing late models - the fastest and most complicated type of stock cars raced at the local level - at the same track. That season, he won his first feature race, at Leo's Speedway in Oshkosh.  Kulwicki moved from dirt tracks to paved tracks in 1977. He also teamed up with racecar builder Greg Krieger to research, model, engineer, and construct an innovative car with far more torsional stiffness than other late models. The increased stiffness allowed the car to handle better in the corners, which increased its speed. Racing at Slinger Super Speedway, he won the track championship in 1977. In 1978, Kulwicki returned to Slinger; that same year he started racing a late model at Wisconsin International Raceway (WIR), finishing third in points in his rookie season at the track. In 1979 and 1980, he won the WIR late model track championships.  In 1979, Kulwicki began competing in regional to national level events sanctioned by the USAC Stock Car series and the American Speed Association (ASA), while remaining an amateur racer through 1980. When Kulwicki raced against future NASCAR champion Rusty Wallace in the ASA series, the two became friends. Kulwicki's highest finish in the ASA season points championship was third place, which he accomplished in both 1982 and 1985, with five career victories and twelve pole positions.
