The problem w/mtn fires is how easily they can start (neglected campfires, lightning, broken glass prisms, fireworks, kids malicious mischief, cigarettes, automobile backfires, homeless encampments, etc) and how dangerously fast the mtn fires move, how forest fires create their own fierce drafts to spread very rapidly in such large areas that fire fighters and air drops are hindered to contain the rapid spread of forest fuel ~ but the worst part is that most mtn roads are narrow or have just one road in/out that jams safe evacuation/rescue efforts. City or suburban home fires have more contained combustion and 2 or more local fire units can respond in minutes to put out residential fires quicker. Mtn fires take hours sometimes to organize firefighting efforts. Things are improving to fight but never underestimate rural or forest fire dangers.
