This track has a completely unique layout and scenery, with it's banked turns and grandstands it feels very much like a pre-war racetrack.
Technically, it can be installed over any NFS4 track, but because it's a racetrack, in my opinion it would make sense to install it in one of the GT1-GT2-GT3 directories. (Pictured is GT1). Because it is based on Dan2k's conversion of Lost Vegas, it sadly suffers from the 'collision bug', meaning that you'll need caution through the tighter parts, or you'll be stopped dead in your tracks.
