No joke, one of the buildings in my apt complex caught fire last night. Not sure if it was from fireworks or not, but probably. Haven’t been by to see the damage, but I could see the smoke in the night. I think they got to it pretty quick.
So it looked to me cinders from one of them came down into one of the mortars and caused it to explode and start a chain reaction. Though I suppose something else could have caused that.
