Located on 890 acres just outside of Austin, TX, the Circuit of the Americas (COTA) is a 3.4-mile motor racing circuit. It is the host of the Formula One United States Grand Prix, the Motorcycle Grand Prix of The Americas, the FIA World Endurance Championship, and the Tudor United SportsCar Championship. I photographed it during a day trip to Austin which started at 4 am in the morning and ended at midnight.
