John and Mary Smith had ordinary names, but their extraordinary 60-year marriage was anything but that, ending with her death one year ago.It had to be a marriage made in heaven, because they hardly had any planning time during a six-week courtship between their initial blind date and wedding in 1961.They defied norms in many ways, including construction of an octagonal-sided home which has no hallways, and travel that took them to many parts of the world. Parents of two adult sons, they crowded much into their years together.John tried hard to keep pace, but Mary set a tough course.
