AFAIK mate the new 4X track isn't open yet, they're still working on it. There was a video put up here a couple of days ago saying it wasn't done yet, if I remember right, so I can't see it being finished yet.
However on the note of Goat Farm and the public, is it a public track open for whenever? Or a private race/event track? I always thought it was the latter but from what I've been hearing recently that's not the case?
