I live in the county with multiple acres - water well, propane tank, septic system, etc. I let the gray water (washing machine, showers, etc.) run on the ground. To me it's the same as washing your truck, etc. I learned that from my grandfather in West Texas. Just my 2 cents.
I have had several lighting strikes out here and my insurance company has done me well replacing equipment - even had a strike once that blew out the windows on one side of the house. Several large trees here. A previous post was right, a large (5/8" diameter) copper rod 10' deep driven into the ground helps alot - for me at least.
We will see you at Toledo Bend. Good luck Skip!
