Well its like hunting rats in a totally black, dark room.
One listens for the sound of them scurring about.
Then toss some food at them to occupy them
and side track them, keep them busy while you
go to work.
Then you take a delicate, high feed back fishing
pole that can reach around the whole world in one hand and carefully
probe them, gently run it over the rats
till you can feel the outline of the rat from the
fishing pole touching the rat very gently.
In the other hand you have a steel pipe the same length
as the fishing pole.
If he runs you keep it up till he gets used to
the tip of the fishing pole touching him.
And he sets still while he is petted with the
fishing pole tip,
Remember its totally dark, you can't see anything.
You can hear and feel around with the tip of the
fishing pole. But you are blind.
Once you have Id the Rat and are sure its a rat,
Right height, 3 ", tail and about 2 or 3" wide
and squeeks, and you know exactly where it
is you quickly move the fishing pole tip out of
the way and beat the hell out of the rat with the
steel pole in the other hand. While you see nothing.
Then you sit back and listen,
Eventually you put the fishing pole tip
back in the room and see if the rats body
is laying still, if it moves or bites the pole,
you beat hell out of it again.
Once your sure its dead you lay microphones ( BSU's)
to listen for any more of them scurring about and
go on to the next dark room with your target.
