The people running the fair had a warning of heavy winds and rain two hours before it struck. I know it's hard to tell people they have to leave when they are spending so much money. That was dumb. The money they will lose when the injury Lawyers finish feeding will be considerably higher than what ever profits they made from cokes and corndog sales in those last two hours. Finally, someone told the crowd there really was a storm coming and they needed to leave. Five short minutes later, death and destruction came calling. Dumber was ignoring that warning and paying with your life.
Once again, Mother Nature trims the herd.
