Yes, yes, yes.  That has nothing to dso with the subject at hand.

Lightning is an issue in every state.  It's just a more frequent one
here in SW Florida.

I've dealt with the aftermath of lightning strikes on or near
numerous structures in CT.  Most frequently the damage is caused by
ground strike lightning.  When it hits the energy spreads out much
like ripples on a pond.  As it spreads out from that point, traveling
along the surface of the ground, it looks for the easiest path.  If
there are multiple grounds on a structure or on a group of
electrically interconnected structures, current will flow in through
one ground and out through another.  That's why a bonded ground is so
important.

Naah.  That would only mean that I had either studied xerography or
broken into a museum.  My favorite Lichtenberg aphorism: "If
countries were named after the words you first hear when you go
there, England would have to be called 'Damn It.'"

That's OK.  He can just be wrong in Spanish.  I don't mind.  :^)
