That's awfully selective, Jerry. The article also says, "It is a common
misconception to think that a lightning strike will blow up a concrete pad."
As for the "certain circumstances," they say, "We have only seen this
happen once on a mountain top in the Nevada desert. However, a few poorly
implemented occurrences can give a valuable technique a bad
reputation." In addition. the case they describe involved J-bolts, not a
rebar cage.
What was said at the beginning of this thread was nothing but a restatement
of the common misconception.
