a group I used to race with had an event there.
I saw some in car video of the place and decided to pass on the event.
the track layout looks like good fun, but there is not any runoff in almost all of the turns.
to me it didnt look like a very safe track to go racing on.
the guys who went said it was fun, but I wouldnt make the trip if it were me.
here is a link to a video

there are some areas that the track just drops off on the edges into the dirt, and there rest is walls.
HPR looks like its a blast from what I have seen.
