I was once driving to work on the Garden State Parkway; it was three lanes of heavy stop-and-go traffic due to the rain storm. Suddenly, it turned into an absolute downpour and traffic stopped. Then, lightning began striking trees on either side of the roadway; I counted at least twenty strikes, so it must have been thirty or so, over the course of a couple of minutes.
Then it stopped, a few minutes later the rain lessened and traffic began to move again, and ten minutes later the sun was out when I finally got off the Parkway.
It was the damnedest thing. Maybe a D&D wizard was practicing his spellcasting nearby? Still, thirty strikes, how high was his level?
