When I noticed you can go to the karting track behind the grandstand if you follow the road out from the paddocks my jaw hit the floor so hard I saw stars. 5 of them to be specific.
The track surface geometry feels great to drive on, textures are colorful and varied. It's been a long time since I tried this track elsewhere so I can't say how accurate it is but that definitely hasn't stopped me from having a great time racing/drifting here. Thank you dev!
