Evelyn Dunn, whose backyard fence is directly next to the field, explained she didn't realize what was burning at first.
She recalled, “We were sitting in the living room and all we saw was a cloud of smoke and I was like 'Oh my God somebody’s house is on fire.'"
Dunn said she quickly realized what she was seeing was not a house on fire.
"And then it's like 'Oh my God, the field!'" Dunn recalled. "So me and my daughter ran to the back and it started getting closer and closer and closer, you can’t see anything, it's just black smoke."
Dunn said that neighbors began proactively helping one another hose down their properties as they watched the fire draw closer.
Then, Dunn and her family were asked to evacuate.
When they returned home, they saw the fire had burned their fence but didn't go any further.
“It already started to burn up the fence, with the dry brush, we wouldn’t ve had a chance,” she said.
"Thanks to the Vallejo Fire Department, because if it wasn’t for them, our houses would be gone," Dunn emphasized.
