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.
