A moment in time. It's rare for a person to remember exactly where he or she was at a single moment in time, some four decades later. It's rarer still for an entire nation to hold a collective memory of such a moment. This kind of hardwired retention usually results from group trauma -- the shock of assassination, large scale tragedy, or natural disaster. Occasionally, the event that galvanizes a population is a happy one. Such was the case when Paul Henderson scored the memorable goal in '72, that won the game and united Canada. The Goal that United Canada contains 72 stories that revolve around the '72 Summit Series between Canada and the Soviet Union. Viewed separately, they are very personal, even intimate in nature. When they are strung together they begin to tell a larger story, a uniquely Canadian story of love for our country and its game.
