Ah yes, love Harlan Ellison though I didn't identify with references. The only author I know to do that (other than the multiple references to Hawaii where we live now) is Baldacci, who made several references to the tiny ville we occupied for 6 years, Stanardsville, VA. He even spelled it right (no D after the N).
BTW I read somewhere that the BBC is talking about doing a Discworld series.
