Last day of OMS17

I gave my talk in the first session of the day and, being the morning after the conference dinner, can result in a poor audience. However, there were a few good and interested people there and s discussion with one of them gave me an idea for a small piece of new work. However, he is in the Berlin group, and it would have been cheaper to go there than Cuba to have the discussion. But that's the way if the academic world. In the evening we went to an excellent-looking club, but it was closed so we were frustrated.
