Very common thing in my country. A few weeks ago a homeless person under a bridge in my locale set up a camp fire that got out of control it burnt mostly all the vegetation and charred some of the trees in a forest area. The fire department was monitoring and set there own fires to control it. It went on for about a week and the area was very smokey and smelley. It's amazing cause the area looks mostly the same prior to the fire now except for the charred trees. All vegetation is back and green..
