Firefighters haven’t had much rest during the Fourth of July holidays. They’ve responded to several fireworks-related grass fires, a house fire and even the trailer from where the fireworks show was shot. Granbury Fire Chief Darrell Grober said the trailer caught fire long after the fireworks show over the lake Thursday night. Fireworks officials said the trailer was intentionally set on fire, but the fire chief wasn’t sure. A man woke to a smoke-filled home early Friday morning on Lipan Highway in Granbury. He was able to escape, but the home was considered a total loss, Grober said. The fire began in the attic from unknown causes, Grober said.
