I’m supposed to be on an Air Canada flight to Toronto at this very moment, and thence onward to Athens.
But the trip is postponed to Spring 2018. Alas.
My Russian visa did not come through in time, after the Russian consulate asked for four different, consecutive revisions to the letter of invitation from my colleagues in Moscow.
So I shall keep doing what I do here in the USA for a few more months! Moscow and Vienna await in March, as does London and Cambridge.
