I swear I'm neither insane nor a conspiracy theorist..
Now that we have that out of the way;
At one time I didn't have my clubs regripped for a few years. Because of the spastic motion I have at the top of the backswing, I basically wore the right hand thumb part of the grip (I'm left-handed) to the metal.
I was playing a course in NJ where a hole ran under high-tension wires. When I would ground the club, I'd get a noticeable shock through the thumb hole.
I figured that was likely some odd phenomenon until later that year, club still not re-gripped, I played at a course north of Harrisburg PA where high tension wires ran down almost right over the first tee. It was morning and the ground was very damp with dew. This time I got a shock that was almost jarring when the metal club touched the ground.
Can anyone explain this?
Whenever I hear electric company officials claiming how safe it is to live near high voltage lines I have to be extremely skeptical.
The obvious lesson here is to regrip your clubs often.
