I'm aware of the dirt issue.
It's an indoor pulling hall, based on indoor Zwolle. (If you don't know what it is: http://lmgtfy.com/?q=tractor+pulling )

It features a well lit track, and seats.
I have 2 possible future thumbnails attached, let me know which one you like better.
Do not reupload to a Russian beamng mod website, I'm looking at you Slavaska!
Also, if you don´t have a single clue as to what tractor pulling is, don´t bother downloading and reviewing it, it will only give it a bad rating because people don´t know what it is, thank you.
