I am used to nighttime gunfire around here, but last night a new and strange sound emerged- a loud "BAM", sequenced like gunfire but with an odd, slightly muffled low pitched metallic overtone. Imagine someone striking a 55 gallon drum with a iron pipe or baseball bat. There was a series of them , with some changes in volume and cadence, and a short. much quieter, rapid- bam bam bam bam bam , exactly like a .22 auto. Am I hearing gunfire coming from inside another house? The nearest residence or barn is about 300 yards away. I am hoping it was not a home invasion with the volume change and irregular pattern being some tweaker going from room to room... I guess the news will tell.
