Here is the third CART track, an oval track, Fontana.
I have contacted the creators, USPits, but no reply, administrators of the website did not reply, I created a thread on their forum, no reply. In fact the website seems to be really dead since 2 years...
So, I took the liberty to update this track but you can visit here : http://www.thepits.us/
Credits for them anyway. There is also a donation link but probably abandonned too.
The track is now really better in terms of graphical aspect. Grass, 3d grass, road, road surface, racegroove, etc... All possible stuff.
Hope you will enjoy it in CART, or whatever you want.
Thanks to Denis for loading screen and mini map.
