Chacha, SixTen, Barney--

I appreciate the respectful way you have each asked your questions. I know that none of you agree with me, but the manner in which you have carried out this discussion is entirely agreeable. I suspect that each of my answers has probably brought more questions/comments to your mind. I welcome them, however I need to take my leave to go celebrate my birthday with my wife. I may not be able to return to it until Monday. I share that because I don't want you to think that I have just refused to answer any more quesitons. I'll check back in again later if I can and see if the discussion is still on such positive track. But, even if it has gone awry and I then elect to opt out, I want you to know I appreciated the way in which everyone has conducted themselves in this thread, and your last three questions especially. THANKS.
