San Francisco's new cereal connection involves a promotion with Kellogg's in which 40 million boxes will offer consumers the chance to win a trip to a "Great American City," such as San Francisco, New York, Chicago, Philadelphia, Los Angeles or Seattle. The 6 million or 7 million boxes promoting San Francisco will be "adult" cereals, such as All-Bran and Product 19. "You'll notice that this is not Froot Loops," joked one visitors' bureau executive.
