A wind-driven fire jumped Highway 101 north of Ukiah and burned 30 all-terrain vehicles and about three acres of grass before it was extinguished Monday evening, fire officials said.

Firefighters were able to keep the fire from burning any structures, including the one housing Motosports, behind which the vehicles were stored, said John Bartlett, chief of the combined Ukiah, Ukiah Valley and Hopland fire departments.

After burning the all-terrain vehicles, the fire continued east, crossing State Street and sparking fire on property owned by Masonite, he said.

The cause of the fire, which ignited on the west side of Highway 101 at about 4:45 p.m., has not been determined, Bartlett said.

About 20 of the burned all-terrain vehicles were new, he said. The others were at the business being repaired. Each is valued at about $13,000 Bartlett said.

The fire could have been worse, he said.

"It was really windy that day," Bartlett said.
