Context: I can only imagine that these old time Olympians enjoy seeing that their names are not forgotten , that younger people continue to cherish their exploits decades later . In my first article I talked about Billy Mills , the 1964 gold medalist in the 10,000 run . After returning to Calistoga I learned that he and his wife were in Beijing .
