February - November

I took some time away from the site and list this year. It’s been a weird and difficult time for me: among several other things, my father was in the last stages of Parkinson’s Disease after about eighteen years, in hospital much of the year from January, and finally died in September. And in retrospect, after fifteen years of near-daily effort, it was perhaps time to have a break from the Chroma for a while.
