Pete, did you feel a twitch this day? http://ktla.com/2014/11/28/firefigh...amaged-in-4-acre-fire-at-fontana-pallet-yard/
Sadly this is why cities have ordinances for fire hazards. How exactly Propane and acetylene cylinders "explode" is a different story - sounds more like they were just overheated in the blaze. Has insurance "claim" written all over it
Yikes I bet that sucker was burning hot! Does sound like the possibility of foul play with $3million in property damage.
