Atlanta, now converted for N2003, here:

Road Atlanta, both the real and virtual iterations, is a perfect venue for
stock cars (or Trans-Am or Craftsman trucks), and as good as good as
Noonan's version was for GPL, the N2003 track is even better.
Now, if we can only convince Dave to convert his greatest-ever GPL track,
Imola (which should likewise make an ideal N2003 track), I may yet be lured
out of retirement.
