Nope, never been hit by lightning in over 30 years of hamming. Evidently you have had that misfortune.

Ever wonder if there might be something you don't understand about static build-up?

My tower is grounded by virtue of the tower leg bottoms stuck in sand and dirt below the concrete. I don't need any additional grounding.

The tower acts like a big lightning rod. Contrary to popular belief, lightning rods don't attract lightning, they dissipate static charge. At least mine seems to work that way. Your milage may differ. wrote:

You ever take a lightning hit? I have several times and it was uh....exciting. Towers were extensively grounded but not to a common ground with the house. Three tower legs are not an extensive ground and will not dissapate a direct hit and will likely make a beeline to your shack on the coax to finish the job on its way to your home grounding system through the house. You are living on borrowed time with that attitude. Extensive grounding is your best friend and the insurance company's.

I fail to see why a ground is needed at all. Surely the lower two feet of tower is firmly embedded in dirt with the concrete anchor above that. If it was done that way those three tower legs should serve as some pretty good ground rods. At least my version of common sense tells me so. I will have to admit that common sense has not always been kind. Sometimes it does not make sense at all and becomes just common bs. I am wondering what it might be on this topic? Anyone venture a guess?
