The most interesting thing was the total experience of working with such amazing professional astronomers doing real science. I really did not know what to expect. The experience did exceed, in a positive way, all my imaginations.
I can't begin to tell you what a wonderful experience this week was for me and my students. The skills and knowledge we all picked up were great.
Astronomers, all of whom are scientists, can be personal, funny, and outright social beings.
