John,
One of the town halls I work at has the lightning arrestor system through out all of the buildings. Here in NJ that inspection ( believe it or not) falls under the Building inspector. I watch the system as they go in and make sure they get the certification for the whole system. I have seen some strange things with lightning. I seen where a bolt of lightning went through the side of an old stucco house and hit an old shotgun laying in the attic. That was all nothing else happened. (Beside the small hole in the stucco where the bolt entered.)
