(FORTUNE Magazine) – LITTLE ROCK -- American Civil Liberties Union lawyers ((will)) represent a Ku Klux Klan group seeking to participate in a state Adopt-A-Highway anti-litter program . . . Members of the Knights of the Ku Klux Klan were rejected last month . . . when they sought to adopt one mile of U.S. 65 at the Arkansas Missouri state line. Participants in the program are announced on signs posted along the highways they have adopted. ''I would say that it raises issues surrounding the First Amendment right of free speech,'' ((an ACLU spokesman)) said . . . In denying the request, officials cited the potential for increased litter thrown by Klan opponents and the bad image it would give the state. ''It would be 'Welcome to Arkansas -- KKK,' '' said ((a state official)). -- From an AP dispatch.
