I know, I know, I asked this question once before in another thread, but my answer from that thread stands...........
ROAD AMERICA!!!! Often referred to as "America's Spa"(in honor of Spa-Francorchamps in Belgium), it's an excellent natural-terrain road course that thankfully hasn't been butchered by chicanes or other "safety" features. It's got some very fast corners(the Kink), great passing zones(down into turn 5, and going through the Kink into Canada Corner) and is a drivers' track if there ever was one.
If Formula 1 were to return to the United States, I would hope that the powers-that-be would stage the USGP there. One can only hope......
