Officials must be happy — and a little vindicated — today. The weather cooled off, the breeze came in and the visibility improved. You can actually see buildings off in the distance, which is a vast improvement from the weekend.

Perhaps the traffic restrictions and factory closures are making a difference.

Lastly, I met an NBC producer on the media bus this afternoon. He’s an veteran, having covered multiple Olympics. I asked him how the security in Beijing is compared to Athens in 2004. Athens, he said, was much worse, much more strict. He did point out, however, that he hadn’t gone within the Olympic compound yet.

For a newbie, the heightened security definitely has an impact. But after three days of entering and exiting the Olympic area, I’ve gotten used to all the screening and checkpoints.
