As far as closing parks when there might be a chance of weather, what you would end up with then is not only massive lost revenue, but lots of people PO'd because they closed the park. It is a no win situation and you can't protect everyone from every possible thing that might happen. If folks are at a park and weather approaches, they need to take a certain amount of personal responsibility, but, we know that will probably never happen. I will say if I was there and depending where I was in the park, I would not be rushing to the exit, I would get out of the way like someone else said and maybe hunker down in that tunnel going to TNT.
