Is it okay? I liked dumb shit when I was 13... because I was 13. And look - I'm not saying it's not okay, I just don't understand celebrating it as an event, and I don't know why it's at a theme park.
Wait. Its not even really an event - a monster truck rally is an event. This is a separate event that celebrates the amalgamation of other mindless events. It all seems, at best, silly to me. But mostly a waste of resources the park could be using to do better things.
