Hidden Valley is a 1/3 mile high banked asphalt oval that is fast fast fast !!! One waring about the track though. It does require some processor power to run properly.
Like most short tracks, traffic here will wear you down and bite you when you least expect it, so stay on your toes, as running 105mph lap times around a 1/3 mile track means making circles quite fast and leaves little room to screw up.
If you got this track for the Winter Heats season last year, be aware that it has some slight graphical changes since then so you will want to download it again.
All told, this is one of the finest short track venues for sim racing around. I think you will agree !!!
