If you had any inclination to watch something called a Nationwide Series Race tonight at 7 PM (EST) on ESPN2, you can enhance your enjoyment by watching the TV crew as they televise the event. You can even chat with like-minded people at the same time.
You can see the goings-on in the control room, audio & sub mix, etc. It's actually pretty cool.
Of course it would be really cool if the crew was covering something other than auto racing.
