I'm planning on attending the Phoenix show this Wednesday (Row 6). I called the arena asking about what size limitations were for signs and the security guy said 8x10?! Then, of course, I call back today hoping to just speak to someone in the box office and they had no idea so they asked a different security guy who said NO signs were allowed. Really?! I have a great sign planned and still want to make something reasonably small-ish and just try it... Knowing it varies from venue to venue, has anyone had issues bringing their signs into the concert before? Not totally sure what to do!
