A track in the US is great...but Americanized? i doubt it..just because the way drivers are brought into F1...too much of a big risk to take, and not many team are willing to take it.
As for Watkins Glenn ...its turns are too slanted for F1 IMO, plus they would have to do a lot of things to bring its facilities to an F1 Standard...
Id like to see road america, or long beach
