Sorry, just getting around to posting this. We had quite the display set up in my back field. Had 3 firing areas with stock piles setup behind the shooting area. The mistake we made was having the extra mortars under the firing table. Somehow a spark got under the table and set off a chain reaction to all the firing stations and the 4000 shot finale that was pre wired. All is normal until the 1:03 mark and then you will see the explosion on the ground. Of course the fire department had to be called. :oops:
Thankfully no one was injured.
