I think you would find the changes needed there would be extensive and charm ruining too. Canada Corner? would need the hill cut out to provide runoff area. The kink? couldn't survive in present configuration with the wall right on the outside. Those two alone are enough to ruin the track for me.
I'm all for building the new track and letting the awesome tracks we have stay the same... but being closer than Austin would be nice
corners have names and numbers for reasons
I go to Road America at least once a year, and I'm still somewhat unclear which section of the track you are referring to, though I think you might mean the kink. which comes after the carousel.
