The CDL address at the end of the movie
Near the end of the film, George Putnam (the narrator) tells people to write to the CDL (Citizens for Decent Literature) at a P.O. Box address in Cincinnati, Ohio. The film itself doesn't mention it, but CDL was organized by Charles Keating, who became involved in a political financial scandal ("The Keating Five") many years later.
Does the CDL still exist today? Has anyone written to that address?
