I don't even risk it when I go to shows. Recently venues have been trying to take my wallet claiming they could be used as weapons, especially with metal. I've always called bull on that but it's whatever. I'd rather not get kicked out and enjoy the show. Maybe I should start using more shirts for knife shots. I definitely have WAY too many band shirts in my possession.
Tonight was my first time seeing them and oh my God was it a great show! Seeing them run around and bring that much energy, while being in their 60's, is just amazing to me.
Did they not check you? I needed pockets emptied, metal detector, a pat down and search with the wand. They were more thorough than the TSA
