Later, he managed and coached teams for South Troy Little League and served as commissioner for the South Troy Pop Warner Football league when his son became involved in sports. John loved spending time with his family and taking yearly trips to the Baseball Hall of Fame in Cooperstown, where he held a membership for over 25 years. He was an avid stamp and baseball card collector and was friends with many of the post office employees he visited regularly to see what new stamps were out.
