Starting in July, I served on a Technical, Management and Cost panel helping NASA evaluate Discovery Mission Proposals. Most of the evaluation was done via work-at-home and telecons, but it wrapped up with a two week plenary in Chicago, November 4-15, 2019. This overlapped a holiday weekend, November 9-11, 2019. Panel members had the option to go home and come back or to stay. I stayed and visited the Field Museum on Sunday and the Museum of Science and Industry on Monday (when it snowed!).
