UPDATE 8/9/16 5:29PM: Despite reaching the halfway mark, Cal Fire crews are not stepping off the accelerator.

"Since day one we've had the same attitude towards it," said Rigoberto Herrera with Cal Fire. "We're going to push ourselves to the best of our ability."

The tactics moving forward won't be changing much either. According to Cal Fire, the containment lines, controlled burns, and back burns are working.

"Our windows are very short where we can burn due to the weather, so we're trying in the spots that we can, to back burn," said Herrera.

Cal Fire crews are working to get a hold of the shoulders of the fire, at the southwest and southeast corners. If there's steady containment there, that's good news moving forward, but just like any wildfire situation Cal Fire is prepared for the worst.

"The terrain is different in all the areas, so we can plan for something but it cannot always go the same way," said Herrera.

Residents are also keeping their guard up.

"Of course it's great, but it's a fire and you never know what could happen," said Collin Murray, who lives in the Tassajara area. "It can jump lines, (or) the wind can pick up."

Cal Fire has also reduced the number of crews fighting this fire to 4,800 -- another sign they're slowly getting a handle on this fire.
