Since cartmen34 sent me a PM about the Thursday pit walkabout, I thought I'd also post the response to him here, in case others have questions:
Last year was the first year for the pit walkabout. I didn't go but saw pictures of it. It was a huge success, probably too successful. Was very crowded. Was difficult for many to see anything. The cars were in their garages and there were barriers erected for the fans to stand behind. I've got mixed feelings on the event. Some people raved about it, others were upset that they really couldn't see much due to the crowd.

Also here's someone's photo gallery of the event from last year that shows how it was configured for last year. If you go I'd definately show up really early for it.

I'll be in what is T1 for the USGP - T4 on the oval. Great seats. Recommend you walk around in the infield during practice and qualifications to see all the infield corners. Some parts are much more interesting that others.
It is an awesome experience. And loud.
BTW - if you really want to get close to the cars, you can watch them leave the pits from the tower terrace seats, just below the victory podium. At pit out many times they will pull up and practice their launch. You must wear ear protection to stand there, its is amazingly loud. Great spot for photos or video.
