Here's a post from the MRA president....check it out!
sorry if it is a repost.....

OK, there have been a lot of very respectable attempts to simulate what a lap around our new track will be like from a riders/drivers perspective, but based on the latest developments in the track design and what I personally know about the layout of the land, etc...
THIS is absolutely THE BEST simulation I have ever seen. In my opinion the only way you will get any closer to a lap at HPR is to actually drive it.
