LOS ANGELES (KABC) -- As the decades tick by, we often forget an event's origin. More importantly, we forget all it took to make the event happen in the first place. 56 years ago, the very first Pride parade was a breakthrough event. The culmination of rage, courage, and a desperate fight for equality. A Harvard study says that joy is contagious. A person's happiness is influenced by the happiness of others. But there is so much more to the bliss that you see in the film of the first Pride parade.
