Grass fires damaged at least 10 homes and burned about 1,500 acres before crews were able to control them late on July 30, authorities in north-central Oklahoma said. Seven mobile homes and three houses were damaged in the fires in Payne County, said Stillwater Fire Marshal Trent Hawkins. "We’re in the process of releasing a lot of departments that responded from other jurisdictions, but we still have a lot of hot spots and flare-ups that are being reported that we’re sending units out on," Hawkins said. "At a minimum, there will probably be two Stillwater units out here all night."
