There are things I carry that don’t even cross my mind for a list like this but there they are; my 9 & 10 are keys and sunglasses.

Back east my list would be different. For one I’d have a Metro-card or two and my briefcase carried a lot of stuff. I could date myself by saying I had a Gerber Guardian clipped inside my briefcase and none of the security guards gave it a second glance; they didn’t care about something so benign. I don’t carry that briefcase any more, but the Gerber Guardian is inside.
