Quix - Thank you for the ping. It was informative and I appreciate your keeping me posted.
Contrarian - The “Burl Ives” he was hanging out with. Is that the same Burl Ives most of us are familiar with, the entertainer? If yes, what did he have to do with Carl Sagan, etc.??? If not, please excuse the stupid question (just being nosy)
Thanks for your kind words.
