The Kurt Martin House, the site of Mason's first private club, was built of concrete blocks cast locally. Notice the color bas-relief of a Hereford bull at the peak of the garage. Past occupants of the house kept Nubian goats in the back, which has a concrete block fence around it. One goat, Opal, liked to jump up on top of the fence. City work crews across the street would yell at her to get back in the pen, and she would promptly obey. Soon anyone driving by knew to yell, "Opal, get back in your pen!" whenever they saw her on the fence. Charles and Loretta Elbel, the current residents of the home, have preserved the architectural integrity of the structure and its environs, while "spiffing" up the area.
