|  If you stopped to think about what you are saying you'd realize how
|ridiculus it sounds.  If a bolt of lightning (MEGA volts at MEGA amps) struck
|the lightning rod sitting on a wooden barn or house, you would really be
|talking FLAMES.  Even if the wire cable that would be carring the current to
|ground was low resistance, at that current there would be a LARGE voltage drop
|across the cable.  The power disapated would heat the cable red hot; not 
|exactly something you want attached to your wooden structure.

How do you account for those real pictures of lightning rods on tall
skyscrapers taking hits?
