Missed the demo today. I had too much to do, getting ready for a trip to the Mainland coming up. We are going to see our grandkids after too long an interval. Last time we saw them was in July. Also we'll be attending a memorial service for Terry's uncle, Victor Scheffer, who died at age 104. He was a distinguished marine biologist whose books were best sellers in the 60's and 70's: The Year of the Whale was the most popular and was influential in arguing for banning whale hunting. This will be a happy occasion: he had such a good life.
