The good news is that of all the shows I've had this one seems to be the best fortified against terrorist attack. The bad news is that access to the show is somewhat limited. In order to see it, you'll need to spend several hundred dollars on a ticket, submit to a strip search, empty all liquid containers, remove your shoes, and go through a metal detector. Hopefully you were already planning to do all of that anyway.
