	Have you ever tried driving an 8 foot (or even 6 foot) rod into hard,
gravelly soil?  I have and, at least around here, it's just about
impossible.  In soft and moist soil it should be easy, but not in this
part of Southern California.  I tried to drive 4 such 6 foot rods into
my back yard and didn't get any of them deeper than about 4 feet.  After
that fiasco I went to the copper pipe/water method and it worked fine.
