Engineer Edward "Ed" Butera spent hours constructing models from the time he was a five-year-old boy in San Jose, California. Besides his interest in building and design, the young Butera also loved math and music—specifically the clarinet, at which he excelled, and which he still enjoys. After earning his Bachelor’s degree in Electrical Engineering at San Jose State University he was hired by Ralph Joeckel as a consulting engineer for Trane, a heating and air conditioning company. Joeckel became a mentor and "second dad" to Butera after the company sent him to Las Vegas in 1972, and the two remain close to this day. In this interview, Butera shares how he engineered and designed power, water, sanitation, utilities, and heating and cooling systems on many Clark County high schools, hospitals, and data centers while considering such factors as the building's shape and its affect on the way wind forces act on its glass, windows, and doors. He talks of his casino work that began with the Stardust soon after he arrived in Las Vegas, and before his client list grew to include Tony Marnell, Steve Wynn, and MGM. Besides the hotels, he shares his experiences engineering the infrastructure for the Bellagio fountains, The Mirage volcano, Treasure Island's pirate show.

Dennis Ortwein arrived in Las Vegas in 1956. He shares many details about growing up in Montana, his parents and siblings, his education, and the moment in time when he was offered an opportunity to work in Las Vegas. He also lays out the path his singing career took, starting with school plays, duets with his sister, and high school quartets. Once in Las Vegas, Dennis taught for a while, served as principal, and was involved in creating programs that helped integrate schools. He also talks about his church choir work, entertainment in early Las Vegas, above-ground testing at the Nevada Test Site, and anti-nuclear protests. Dennis served as lab school and student teaching coordinator in Nigeria. He offers several anecdotes and stories about the time he and his family spent there. After retiring early (age 53), Dennis acted as consultant to the Esmeralda County school board, executive director for the National Conference of Christians and Jews, and wrote a book. He is currently enjoying his singing career by appearing at conventions, in musicals, and at weddings and memorials.
