Thank you for saying it. The USA is quite large, and that means we have tons and tons and tons and tons of warehouses. With that being said, warehouses are actually quite flammable- often filled with paper packaging, flammable materials, and fine dust made of cardboard particles. It's not unusual for them go to up in flames and smoke, and the rate we're seeing them burning seems about on par with the average number of normal warehouse fires in a week.
