I am going on a short trip and plan to take a D70 with attached lens, an extra battery, several memory cards, and perhaps a battery charger. I'm assuming TSA won't give me any problems about such items. I plan to carry the camera about my neck and the other items either in carry-on baggage or in my pockets. Any advice about how how to speed things up when going through the security gate? Sorry for asking these questions, but I haven't travelled with a camera for a while.
