I was not gonna be home, so I set the DVR to record. So anytime there is a last minute change to the schedule, the DVR will not pick it up and we have other events recorded. Totally sucks.
Also, as others have mentioned, the Penn TV production was atrocious. They were literally calling one of the 100m W races and the camera was showing women on the start for the the 1500m. The finish line camera was also terrible, looked like it was shot by someone in the stands. I don't recall if it is like this every year.
