This weekend is the second hosting of the United States Grand Prix at Austin.
The Texas track has already impressed much of the Formula One fraternity for its cresting layout and sweeping turns, and the entertaining battle for the lead last year.
But this weekend will be the litmus test.
After the usual first-year hurrah, will the Austin track keep attendances up?
The suggestions are that it will. But why has it taken until this decade for F1 to get a foothold in America?
In a country dominated by NASCAR that has its own IndyCar series, meaning it boasts a top-level single-seater championship already, Formula One has stiff competition.
Is it the circuits? To a large extent, perhaps. Because, while there haven’t been many circuit tracks in the US, they have been a mixed bag.
Few have stood out, except one or two. Is Austin among them? Find out now.
