After the tunnel, there are some more lights as you drive around the outside of the racetrack.
Next, the course heads under the grandstands. We really loved this section. Not just for the lights, but we found it pretty cool to drive through this area of the racetrack. How often are you able to drive in locations like this?
Anyway, the grandstand gives a long tunnel effect. However, it can get quite backed up on busy nights. If you can, try to give yourself a little space between the car in front of you. You’ll enjoy the experience a lot more.
