I will add 1 thing because it became a pain in the rear.

If your not a racer, no parking in paddock. You can walk through but no parking.
I spent 10 minutes trying to move 20 feet because someone was looking for a spot to open up. He then took another racers spot and some words took place.

Even though I was not a racer this time. I felt there was no need to park there. It was hectic enough!
