	I know some of the "big boys" will object to this, but can't see any
fundamental reason for a GOOD ground, other than the very important one
of protection from getting across the primary transformer circuit via an
arc and 60 cycle conduction along the ion trail.  There is the question
of RF interference, but that is not fundamental to the operation of the
TC.  Can't see why the streamers would ever be improved by having an
effective ground plane more than a few coil heights in diameter.
