Well, I'm 16 and I'm going to Chicago in a couple of days for a concert. My issue is Chicago's laws. I know that I cannot have a knife over 2" since I'm under 18 and even then, it could only be 2.5". This concert is going to be at the Bulls' stadium, so there is bound to be some searching/metal detecting. Any ideas on what I should take with me? I have a Mossberg Tactical Pen (Not my first choice, but what else!) Any ideas on what I could take, that I could explain to stadium security without getting a cavity search in communist hell?
