 The lights on the 1981 tree suffered from faulty wiring, and could not be lit on the final night of the event (January 1, 1982).The year 1981 also marked the beginning of a number of changes to the Pageant of Peace.The petting zoo was canceled due to cost concerns, but for the first time each state or territory donated the ornaments to be used on their tree lining the Pathway of Peace.
