A rare public appearance by Prince William Tuesday in Vancouver, B.C., was causing quite a stir.

The 15-year-old prince, his father, Prince Charles, and his brother, Prince Harry, 13, planned a full day of public events around Vancouver before heading to the Whistler ski resort for a private vacation.Thousands of people are expected to line the streets outside two stops on the royal itinerary, but the visit will be so brief that royal watchers will be lucky to catch even a glimpse of William.
