MYTH: Lightning only strikes good conductors like metal.
TRUTH:This can be a deadly assumption. Lightning can strike any material that is in its path. True, the lightning current is more likely to flow through good conductors, but like the first myth, lightning will strike the best conductor in a particular area. For instance, if there are two posts of the same height in a field, one wood and one steel, if they are far enough apart they are both equally vulnerable to a lightning strike. Only if they are close enough together will the lightning be more likely to strike the steel post. Some people think that riding a bicycle in a storm is dangerous because you are touching the bike's metal frame. Riding a bicycle in a storm IS dangerous, but you are just as likely to be hit by lightning if you are walking or riding an all-plastic vehicle.....the metal bike has little or no effect.
The same applies to golf clubs: Holding a metal club, even in the air after a swing, has little or no effect on your chances of being struck by lightning. The difference between lightning current flowing through a good conductor and a bad conductor is this: Good conductors suffer little damage from lightning while bad conductors are generally severely damaged. Compare this concept to an electric heating element. The heating element glows red hot, while the wires connected to it stay cool, because the wires are much better conductors than the heating element. If lightning strikes a bad conductor like wood, the current will either flow over the surface with little damage, or flow through the material with destructive and explosive results. This is why some trees are totally splintered by lightning while others are unharmed.
