With respect, I'm not sure I agree with all your points.<br><br>I started down that path myself, but I decided that while there are a lot of "important" things to have available during the day, I still think it's better to not dilute the concept of the urban PSK. It really is intended for life-threatening situations, and it just grows out of control if you start adding convenience items- and you raid it too often.<br><br>Not that they're not important- as you point out with the tire example, a job can depend on such things. I had a boss once who kept an entire spare suit, shirt and tie hanging behind his office door. I have a container I keep in my office desk drawer that has a sewing kit, nail clippers, disposable razor, safety pins, pain pills, disposable cutlery, napkins, folding comb/brush, duct tape, tweezers, and that sort of thing... but I wouldn't consider grabbing it if the building shudders.
