I must have missed the following in your previous posts on this meeting, CJG. When was the notice of a Friday evening scientific session first made known? Even the enlarged booth looks to be too crowded for such a gathering of experts + audience and attendees---will there be a separate conference room or auditorium reserved for the occasion? This could well be more interesting than the Saturday poster presentation:
The expert panel discussion/presentations looks to be modeled after some others if I understand it correctly, e.g. that sponsored by BMY at AANS in early May 2015, also in Washington. Will each of the above experts make an individual presentation?
