The size and scope of the wildfire that's been burning in the Big Cypress National Preserve for over a week took a small step back Friday with a reduction in fire area and a small increase in containment. Better mapping helped make those changes and placed the National Fire at 35,027 acres burned and at 67 percent contained by late Friday, according to a press briefing issued by the command structure of the wildfire. That was about 300 fewer acres and three percent more containment.
