It has been my experience that "Mother Earth" does not supply a very
low resistance path, even with a large grounding system of multiple
ground rods and lots of, large, bare Copper wire. Much depends on
your soil conditions, but do not be disheartened if you see more than
1 or two ohms. Others may have had different results.
Right. The earth is a big resistor whose conductivity varies widely from
one place to another. I've measured in the range of 50 ohms between two
8 ft copper clad steel rods about 12 ft apart, driven with only an inch
showing. This was at the base of my big tower. This was with a DC VOM.
As Jim Lux noted, not an ideal method.
