The list has sustained a fairly long thread regarding grounding,
lightning, NEC, and a myriad of related and semi-related subjects. For
those with interest as this thread goes off-list:
Jim, K9YC, references Henry Ott in a couple of his web articles on
grounding. Ott coined the phrase, "The hidden schematic behind the
ground symbol." It turns out that the ground symbol [and ground in the
real circuit/system] is a lot like infinity. We can't help but think of
it as a defined place -- unfortunately, it isn't, and lots can happen on
the way down that yellow brick road. So it is with grounding and radio.
I highly recommend Jim's articles to anyone about to build Elecraft gear
[or any other as well], or who is concerned about his/her station
safety. They apply to any situation where a static charge could destroy
or damage something [or kill you], from shuffling your feet on the
carpet on a dry day to multi-gigavolt electrical displays in the sky, to
how hum and noise find themselves into your transceiver, all because of
that schematic behind the ground symbol.

Usual Disclaimer: Jim's a friend, I know he is *very good* at this
stuff, he offers it free, and I have no financial interest in his
group. I just really don't want to hear about an electrocuted ham radio
operator.
