That's the problem with wood houses.Yesterday a distant relative lost an entire wood house up in the campo over here too. Electrical cable started the fire, burnt the house to the ground and a light truck parked in the garage. Really devastating for the family.
It takes so little to get a fire going, and even if you lived two blocks from the fire station, there's not much chance of saving one of those houses once the fire starts, so the good folks lose everything.
Nothing is salvageable.
