VIDEO: Crews were fighting back flames in yet another early-season wildfire.
Sunday in Pittsburg, a fire spread to more than 50 acres.
"We lost everything. Forty years of history was lost today," said Dianna Schepers of the Pittsburg Theater Company.
The fire destroyed a theater company's warehouse. "Where we store all of our sets and props, costumes, sound equipment, lighting equipment, it all went up in flames today for a reason we don't know. They're investigating right now," Schepers said.
"We had a structure fire that quickly spread into vegetation. Crews had to pivot and change their tactic from a structure fire response to a wildfire response," said Cal Fire Battalion Chief Josh Silveira. The Bay Area has seen a handful of grass fires over the past week, including the Crystal Fire near St. Helena, spreading 60 acres and prompting evacuations.
