By the autumn of 1976 Fred and his wife Barbara decided to make a bicentennial trip through the United States. In all, they covered some 12,000 miles, visiting places they had enjoyed in former years and discovering many new ones. There was no thought in Fred’s mind as they drove south in splendid fall colours along the Appalachian chain of mountains from New Hampshire to N. Carolina that he would ever again be concerned seriously with scientific research. He was sixty one, long past the age for such things. Yet unknown and unsuspected he had thrown a casual glance a few weeks earlier in a direction that was to open up in the next four years into the largest investigations of his research career.
