And an old wives tale of the commercial communication industry as well, 
huh Rich?

Of course if the soil is "moist" there is no problem with the ground as 
moist soil provides the lossy conductivity one needs.  But what if the 
soil isn't moist?  Getting down to the ground water is the best way to 
ensure that you hit "moist" soil, particularly in some parts of the US.  
This is why the recommended grounding is with long, deep ground rods.  
You never know the absolute condx of your soil.
