One time I was BBQ and a lightening bolt hit a big post oak tree about 40 feet from where I was standing. I happened to be looking at it and saw the lightening go down the tree and blow bark and a limb off. We live on a hill and so what I did was buy two residential size power poles (probably 16 feet up and 4 feet down) and set them out a few hundred feet on each side from the house. Put a copper rod on top with a big ground wire going down to a standard 8 foot ground rod driven in the ground. My theory is that it is the reverse of what you think. It does not attract a lightening strike, but it does disperse the charge before the lightening can build up to strike. They have been in for about 15 years and still look good. We do not have the frequent lightening strikes on this hill like we did in the past. So you may want to put one up. I have an even better lightening story. A longer time ago, I was mowing the yard and it started to rain so I stopped. But, I was dirty and decided to wash the car in the rain. So, I got out a bucket,soap and sponge and started washing the car. Suddenly, I saw a wall of light off in the distance moving towards me, across the property (say a thousand feet in 2 seconds) and ran over me. It shocked me through the arm where I was washing the car. It was a real shock, and while I was standing there cussing, a few seconds later, a lightening bolt hit a transformer on a power pole about a quarter of a mile away. Knocked the electricity out.
