This was a wonderful post Guy, and I agree with your logic
concerning anecdotal evidence.
My great aunt was sitting in the kitchen of her farmhouse whipping
up some brownies when a softball sized ball of lightning came
rolling in the door. She was sitting on a high stool with 3 metal
legs. The ball rolled between the legs of the stool, made a circle,
and rolled right back out the same door it had entered. My aunt was
unscathed, but it absolutely scared the tar out of her and created a
family ledgned which has been retold countless times at
get-togethers. The only thing for certain about lightning is it's
uncertainty.
