lomapaseo;
Of course, you're right...I just didn't want to use the term 'fun' but for those who take to puzzle-solving and examining "the trace", even ones with serious and tragic origins, it is, (as I observed), "what we do", so to speak. The other aspect of this is the discussion itself, in public, which is often helpful for those who may be affected or who are seriously curious about the how and why, even if the general facts within Occam's famous notion are known but who may not ordinarily see or even take part in such a discussion. The thread is among the best in a number of excellent threads on PPrUne and for me, is the singular, fundamental value of such a place. And then there are those who live in JB-land...aiyaiyai...
