Lightning never strikes twice in the same place.
You have probably heard this widespread saying. Would you be surprised to learn that it is actually a myth?
Lightning can strike any location more than once. More than this, the second striking is inevitable with enough time given to the Mother Nature.The striking may repeat within a single thunderstorm or a billion years after - lighting will strike the same spot not even twice, but several times. The electrical activity of the storm doesn't change with a strike, and the previously hit location is then just as fair game for the next discharge as any other spot.
This can be interesting: In June 2014 the Sears (Willis) Tower in Chicago was struck by lighting ten times in a row!
