I was at the Midwest Gun Traders show at the Allen Co. Fairgrounds on Sunday when all of the sudden a loud bang ie gunshot went off...then a puff of insulation fell from the ceiling. Everyone was startled, nobody was injured. The shot came from a particular display table but nobody claimed to have known what happened? Seems like when there is a shooting with hundreds of bystanders/witnesses but "nobody knows nuthin". Anyway the local deputy on duty was investigating.
