Being an old racer myself, I got a ground tour of the COA facility last fall and a great bird's-eye view of it when taking off from the Austin airport. It it absolutely top of the world-class category. All my Austin old-time racer friends are blown away that it is located in their midst.
A friend who went to the first race was disappointed that there were no track tickets that allowed the holder to walk around and see the race at different corners. He had to choose one and stay in that area.
As for the guy with parking on turn 10, one of my friends who lives out there tried something like that and got shut down. There was no parking allowed except official lots with shuttles to and from the track. That was because the locals tried to prevent building of the facility because of anticipated high traffic in the area.
Whatever, have fun! I fondly remember the day decades ago when we ran across the entire world Formula 1 field on two open transporters at a service station. I have a Brownie box camera photo of it in an album somewhere.
