Yes, Tom; it was a sleepless night. I still don't know exactly why, except to say that it meant my already being awake when I received word of the death of David Bloom, reporter for NBC/MSNBC. He was not a close personal friend, but we did share ties which made this news personally heart-felt.
When I'd posted the "reminder" I was finding it amusing that we'd both replied within minutes of each other to the query of insulation.
