The fire burned seven acres and crews will be in the area through the afternoon and evening to put out any hot spots. 175 firefighters were involved.”This footage from local resident Aragorn Lesicka shows thick smoke and flames rising from the hills, and helicopters heading toward the fire on Wednesday.
