Once the home of chewing gum king William Wrigley, this Orange Grave Blvd, mansion now serves as the headquarters of the Tournament of Roses Association. Filled with television cameras and shivering boy scouts bearing float banners every January 1, Wrigley Mansion is the year-round home to a wealth of Pasadena history. Aside from the pictures of Rose Parades past, visitors can stop by to view Tournament aficionado Gene Autry's cowboy costume, the bathroom where the President Dwight D. Eisenhower once locked himself for hours shortly before the parade's start and all the marble a fortune in Doublemint could possibly buy.
