You could buy an inexpensive plastic water pipe adapter (less than a
dollar)that has threads on one end of the adapter and a long (I think
they are sold in lenghts about ten feet long) rigid plastic water pipe
at a Home Depot store (or similar stores) and see if a plumbing shop
will glue the adapter onto the pipe for you.Screw the adapter onto a
water hose and turn on the water.That will make it easy to "predrill" a
hole in the ground for the metal grounding rod.Some plumbers use a
similar technique to "predrill" holes underneath sidewalks so they can
run wiring or metal pipes/tubing under sidewalks.Hey,if ya strike
oil,dont forget about me.
