ELROY, Texas -- The buzz from fans around Circuit of the Americas competed with the buzz from the race track.
"The crowds are great! The track is amazing," said Robert Gamblin who was visiting from Arlington.
The race this weekend marks the return of the U.S. Grand Prix.
"I've been to the one in Belgium a few years ago. It's definitely different. Great facility, brand new track, everything's been great," said Raymond Chung from Canada.
On day two of the U.S. Grand Prix, excitement was building. F1 drivers were gearing up for Sunday's race.
After a day of practice runs, they took to the track once again Saturday morning vying for the best position. The drivers zipped around the 3.4 mile course at 200 mph, taking in all 20 turns.
Fans took in the sights from the bleachers and the grassy knolls. Many already had their pick for the win.
"I would like to say that I just want to see a good race but I want to see Button win," said Pamela Aird from Canada.
"Alonso! Alonso is the man. Fernando Alonso. He's gonna win," said Jeffrey Harper from Lubbock.
"You know, Sebastian Vettle is really fast. He always is. A new track, he's pretty adaptive so I think he's gonna be on top," Luke Williamson from San Antonio said.
COTA is expecting about 120,000 fans at the track on Sunday to see who ultimately gets the checkered flag.
