Lee Casey wrote for the Rocky Mountain News in the early 1900s, back in the days when columnists were often far more interesting than the events they chronicled. Casey, for example, was so renowned for his peculiar behavior that he was rumored to be the model for the lead character in Harvey, Mary Chase's play about a fellow whose best friend is an imaginary, six-foot-tall rabbit. But it was in death that Casey's true eccentric nature emerged: He wanted his ashes interred within the walls of the Rocky Mountain News building. They were, and when the tabloid moved to fancy new digs on Colfax Avenue over a decade ago, Casey moved with the paper. Today his remains are still contained within the lobby walls, and there they will stay -- despite the fact that the building now bears a placard announcing that it's the home of the Denver Newspaper Agency, the managing entity of the joint operating agreement between the News and the Denver Post. Casey must be turning over in his you-know-what.
