On Monday I had some time to work on upcoming lectures before meeting Biss.   Aaron’s work schedule is still too complicated to allow him to join us.  The visit was too short, but it did give us time to discuss in more detail  some of the evidence questions he has been working out.  We also discussed the meeting the day before with the other group.  

I left the next morning for my return to Prague.  Changes in the European airline industry have made this a more complicated trip, but I arrived safely Tuesday night.
