So I am going to be in the passenger seat of my dads car as we drive south for about 5 hours. At one of our hotels I was thinking of going out and getting some goodnites. Do you think I could pull it off without him noticing? Also we will be going to state capitols which most require a metal detector. Would I be able to go through that without a problem? I'm sorry if I seem uneducated about the matter but I have only worn in public once or twice before.
