I think the drilling method is okay.  It may not be good in arid climates,
but a few good rain showers will re-pack the dirt around the rod.  In dry
earth it's always good to use electrolyte to enhance conductivity.

To the List,

   As for the water-driving technique shown on the website offered a few
days ago, I have a question.  This technique is very clever, but I have read
that it's important to drive the rods into hard-packed soil so there is a
lot of contact between the rods and the soil.  Pre-drilling a hole for the
rods and then backfilling is explicitly not-recommended, unless you are
doping the soil with electrolytic stuff.  I would think that using the
water-drilling method would produce the same problem as a pre-drilled and
backfilled hole.  Does anyone have comments on this?  If I run into trouble
driving the rods, I would like to use the water method, but not if it makes
a poorly grounded rod.
