While Vern worked for the government, Millie helped the children – Jerry, Mickey, Diane, and Rex – with the business. With the help of their step-grandfather, Orem Ingram, the children built a frontier town on the property. The business quickly expanded into hay rides and delivering the ponies to birthday parties and other special occasions.
As the years passed, the country surrounding the family’s home turned into a city. Many of the places that were used for taking customers on hay rides disappeared. Then, the family home burned down and they were forced to rebuild. Because of the growth in the area, the city zoning ordinance required the frontier town to be taken down during the reconstruction. Despite these setbacks, the children continued running the business of delivering ponies. The boys developed other interests but Diane continued running the business. She then married and started her own family all the while delivering ponies.
