Well about ground rods, I doubt that when your dealing with millions  of 
amps and volts by a lightening strike that a little or a lot of corotion on 
a rod is going to make much difference.  lightening is funny stuff, I was 
leading a what we called a whip horse pulling hay up and into a barn which 
had a metal roof with steel cables out of the barn on both ends and it hit a 
cow and killed her near by so it puzzles me as to how it works. I would have 
thought it should hit the barn.  It scared the crap out of me anyway.   73
