I happened upon this one day. There is no permit. The owner was ridiculously indignant. I mean, you know, way more than he had a right to be. He had a bunch of children to admire and love him . The wall that this guy figured on building was way less than the wall he needed. He was able to afford a chain link fence. Then I was transferred and I don't know the outcome. It might be anything by now....make a great firing range.
