Plaque Honoring Michael Landon Is Returned to Park You don't have to share the Cartwright family's spirit of frontier justice to appreciate the return of a plaque honoring the "Bonanza" star Michael Landon to a park in Collingswood, N.J., where the actor grew up, months after it was removed under unclear circumstances. In January, a local weekly newspaper, The Retrospect, said that a reader had come to its offices bearing the marker honoring Landon, who died in 1991, and who lived in Collingswood before going on to find fame on television shows like "Little House on the Prairie" and "Highway to Heaven" (not to mention films like "I Was a Teenage Werewolf"). The Retrospect said that the plaque, which was displayed at a small playground whose equipment had been financed by Landon's widow, Cindy, had been found in a "dump." But Jim Maley, the mayor of Collingswood, said the plaque had been removed in November during a cleanup of the park and was being kept temporarily in a "public works facility." Either way, The Courier-Post of Cherry Hill, N.J., reported that the plaque has been reinstalled in the park, "close to its previous location" near a bench, a garden and other facilities for aspiring young cowboys, pioneers and werewolves.
