A fast-moving fire consumed a barn and two cars stored inside it in the rural community of Penngrove on Tuesday night, fire officials said.

The blaze in the 300 block of Bannon Lane already was blowing up when a resident called it in shortly after 9 p.m., and the barn was fully engulfed in flames when firefighters arrived, Rancho Adobe Fire Battalion Chief Andy Taylor said.

Inside were a 1976 Porsche 914 and a 1995 Chevrolet Camaro. Both were a total loss, Taylor said.

The barn also was consumed, as were contractor tools it contained, Taylor said. He estimated the damage at $150,000.

Taylor said a little bit of surrounding vegetation was burned, as well, but chickens in a nearby coop survived.

The residence, 75 to 100 feet away, was untouched, Taylor said.

Petaluma Fire crews assisted in the initial fire attack, while Rohnert Park firefighters covered the Rancho Adobe stations. Gold Ridge and Wilmar fire crews responded, as well, but were released, Taylor said.

The cause of the fire near Old Adobe Road remained under investigation Wednesday, he said.
