Lightning fries electronics fast. Mini-surges kill electronics by inches. And nothing makes mini-surges like motors turning on and off. Motors like hand tools and fridge compressors.

A good rule of thumb is that a surge protector's clamping voltage is degraded 25V per inch of wire lead. A single ground rod, far away, won't hurt anything, but its not going to help much either.
