brings up an interesting question though... what about underused existing tracks. I remember as a kid going to LimeRock in CT and watching IMSA Camel GT racing. A quick troll on you tube shows a great track, but armco everywhere (boo hoo) and very scary which is a shame. Check this video for a "drive thru" at a slow pace to get a feel... that turn in the back before the elevation change is totally hairball
