	I'm an engineer at WEPCo, and it just so happens that I work
right next to our stray-voltage expert (Chuck DeNardo).  It also happens
that I know a little something about electricity (it helps, being an EE).

	Stray voltage is a detectable (3 micro-volts up to half a volt)
voltage gradient in the ground which may cause irritation to farm animals
when they are hooked up to milking machines or feeding out of metal troughs
that are grounded more than a few yards away.  Stray voltage occurs NATURALLY
as well as being a result of poor wiring (usually an un-grounded neutral
in the farm's own wiring).
	Basically, it can make a cow not like to eat out of a trough or
not want to give milk (because it tickles), but 
	THERE ARE NO ANIMALS EXPLODING BECAUSE OF STRAY VOLTAGE!!!

	more later...
