Have just heard about this.
Am in the midst of packing, unfortunately, but let me just say quickly that Ray Bradbury's death is the end of an era - he was one of the greats, an immense, and immensely influential, talent. I'm sure there will be many posts and articles today doing him more justice than I am in just this quick notice.
It doesn't seem that long ago that Isaac Asimov, Robert A. Heinlein, Arthur C. Clarke, and, of course, Bradbury, were all still with us. :(
