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.
