Sandra Peña’s story begins in East Los Angeles, where she spent her first fifteen years with her parents (both from Michoacán, Mexico), and her younger sister. The father's managerial position at Master Products allowed the family to live rent-free in a company-owned house behind the main factory, because he collected the rents for the company's two other dwellings. In this interview, Peña recalls the family move to Porterville, in California's Central Valley, her return to Los Angeles at nineteen, and her work with Parson’s Dillingham, a contractor for the Metrolink rail system. She draws the link between the Los Angeles and Las Vegas construction communities by describing her husband's move to Las Vegas to find work; a chance Las Vegas encounter with a friend from Chino, California; her ability to gain employment in Las Vegas at Parson’s, a company that had joint ventured with Parson’s Dillingham, and her move from there to Richardson Construction, a local minority-owned company. As Peña says, "It's kind of all intermingled. Even if you go here and you go there, it's like everybody knows everybody." Throughout, Peña weaves her family story into the narrative as she describes her youth, the birth of her son, the illness and death of her father, and her family's participation in her current employment with Richardson. As she remembers the people, places, and events of her life, Peña speaks to the ways one woman of color built on her interstate construction connections and rose in a male-dominated industry.

For the first 19 years of her life, Mary Martell Shaw called Central America home. Then thanks to misrouted luggage, she met the love of her life Rollin H. Shaw, a civil engineer, at a time in when his atomic energy career was taking off. In October 1943, they married in Costa Rica and for the next two decades traversed the country: Hawaii to California to Panama—wherever a project required Ronnie's engineering skills. Mary supported her husband every step of the way, with every new location. As a traditional homemaker of the era, she became adept at raising their four kids while packing boxes, enrolling them in school and setting up a warm home wherever they landed. The move to Las Vegas in September 1964, however, left her a bit challenged: there was a shortage of adequate housing, a concern for where to send her two daughters and two sons to school, and the feeling that they wouldn't be here long. Years later, Mary and Ronnie would retire to the city where their roots ran deepest, Las Vegas. With great wit, Mary recalls the long absences demanded by Ronnie's work with the Atomic Energy Commission. She also tells stories of the great fun they and their fellow Nevada Test Site employees had at parties, of her learning to paint with watercolors, and the pride she has of all her children's successes based on their education in Las Vegas.
