When the Quebecian vendor Sebastian arrived for the first time three Christmas seasons ago, a flying pig accompanied him. Pink and wired with tiny dots of light and outstretched sparkling wings, it captured smiles and uplifted moods. In magically soaring flight amidst branches and sere autumn leaves, it symbolizes the realization of the impossible. "Yes, pigs can fly. Dare to dream. Make your wishes come true." Fantasy stuff to many? Sure, but to others, inspirational and joyous. Take your pick. As for Sebastian, he knows he can fly.
