Birdsville Race Track, Australia

Once a year, thousands of people descend on the remote town of Birdsville, Australia, for a three-day horse racing event in western Queensland's Diamantina Shire. Commissioned to document the Shire—a 36,000-square-mile area on the edge of the Simpson Desert—Your Shot contributor Rowan Bestmann was covering the event from a light plane when he came across this view of parked 4x4s. "The owners of these vehicles had driven from all over Australia," he says. "During the races, the town's two service stations sell more than 160,000 liters [42,000 gallons] of diesel fuel."
