Interesting Peter and I agree. High objects all the time discharge the
charges above them. How come that on one occasion in Sweden a person was hit
by lightning right in the middle of a wood full with high trees? My theory
is that this person must have been walking and may have moved charges from
one place to the other opening a path for the discharge? The chance that
the person should have been hit is otherwise minimal with hundreds of high
trees standing around?
