I just corrected a major editing error in the piece below.  I should take the opportunity to say that I'm having a lot more trouble with my eyes this year than usual and such editing problems will probably increase.  If it's the allergy season or something more long term, can't tell you.   I do think that my days of online reading and writing may be numbered.  Maybe it's time to brush off those Braille skills I had when I was a kid. Lots of dust on them.
