Twenty years after her birth in Utah in 1924, Marie Horseley met and married her husband who was an engineer for the Union Pacific Railroad. They settled in Las Vegas, his home town and soon purchased a home for $9800 in the new John S. Park neighborhood. Sixty years later Marie, twice a widow, remains in the home. Up the street four doors, one of her granddaughters lives with her three children. Marie recalls the new housing development that appealed to railroad workers. The roads were dirt and there were no streetlights, but soon a community blossomed. Marie is a self-described quiet resident; her life was about raising her three daughters and being a member of the LDS church. However, she knew everyone on her street no matter their religious affiliation. Today the businesses are gone. Homes have changed appearances over the years as owners have changed. Ethnic diversity is apparent and the sense of community closeness has slipped away for her. Yet she loves her place there, feels safe and secure. When asked about the ides of John S. Park being designated a historic district, she is not all that wowed by the idea of restrictions that might be included in that. Nevertheless, she has no intention of relocating from the comfort of the place she has called home all these years.

Lyle Rivera, a relative newcomer, arrived in the 1940s and experienced what he describes as a life of "bouncing around" and being the only child of a single mother, a cocktail waitress at the Golden Nugget.

He modestly mentions his achievements which included involvement with the UNLV Foundation, professional careers in both the Attorney General's and District Attorney's offices,
