Regarding the track stars after event interviews, I have been so impressed with their poise and attitude. I think they have all represented themselves and their country well. I was particularly impresses with Lolo Jones(?), who after hitting that hurdle, maintained her composure during the interview, was gracious, didn't make excuses, and congratulated the other runners. It wasn't until she left the track and was alone in the tunnel that she broke down (understandably so).
That moment was, to me, one of the most poignant moments in this Olympics.
