There was lightning protection on every building (including the chicken house) at a place where I used to live. One day as I was sitting at the kitchen table, lightning struck the combination weather vane/lightning rod on the end of the barn right in full view about 150 ft. away. First of all when lightning strikes that close there is no waiting to hear the thunder as it is simultaneous with the strike. Real scarey! Anyway, there was a shower of sparks at the rod but when I went out to check the ground cable, it was as cool as a cucumber. This system had been installed in the 40s and everything used in the istallation was made of copper including the nails and straps and the grounding wire was real heavy gauge. I often wondered if lightning would have hit the barn if the rod had not been there?
I once worked on a prison farm here in NYS and one afternoon lightning struck a huge maple tree where we had two freshening cows pasturing. Of course they were under the tree to escape the rain. Both were killed instantaneously. The ends of the roots popped right out of the ground and the tree was split down the middle but it survived. We had our own slaughtering plant so we called a couple of the inmate butchers out and
butchered the cows so it was not a total loss.
Lightning is powerful stuff!
