An Oakland man's death during a vintage car rally has been reported by CBS SF.

According to Sheriff’s Capt. Steve Blower, about 35 to 40 cars were participating in an event known as the Bohemian Run. During the rally, enthusiasts drive from Petaluma to Calistoga in vehicles mostly predating 1979. Among them, North of Napa County in Pope Valley, 50-year-old Jordan Hilsenbeck was behind the wheel of a 1969 Porsche.

Preparing to make a left turn, Hilsenbeck was struck on the driver's side by another Porsche, this one from 1989. His friend and fellow Oaklander John David Ravitch, 53, had been trying to get around him on the left at "a high rate of speed." Reportedly, he crossed the double yellow line. Though Hilsenbeck braked suddenly and forcefully, the cars crashed, flying off the road and lodging into a tree.

Hilsenbeck died on the scene. Ravitch and passenger, a 51-year-old Oakland woman, suffered minor injuries for which they were treated at St. Helena Hospital and released, per CHP.

John Ravitch's sister, Sonoma County District Attorney Jill Ravitch, confirmed his involvement in the crash. “Our hearts and our prayers are with the Hilsenbeck family,” she said.

According to the CHP, alcohol or drug impairment did not play a role in the collision.
