Dr. Tyson was scheduled to speak for two hours but it went closer to three and the audience couldn't have been happier for it. He was every bit as charismatic, passionate about science, and informative as we could have hoped. We probably could have listened to him for another three hours. Worth every moment and we'd all go back in a minute. I hope he returns to Nashville again soon.
This clearly wasn't the first time one of his talks had run long because he had this slide ready to go, a (joking) excuse form for the younger audience members who would be sleepy at school tomorrow.
