Riverhead Raceway is a rare beast. For decades it has hosted showdowns between local residents who bring their Mad Max–inspired stock cars to do battle on a quarter-mile track, passions spilling out of the cockpit when the checkered flag drops. Forty such tracks used to exist on Long Island alone. Today Riverhead is the last. Acclaimed photographer Michael Dweck’s evocative portraiture turns the raceway into a theater of catharsis while the track’s owners struggle to maintain an American tradition as a real estate boom surrounds them.
