I was always the one who just wanted everyone to do their job and not get wadded up about mine. I carry a lot of disaster preparedness stuff. I have water proof matches, a cell phone, a back up cell phone, laminated emergency contact info, maps (although I am terrible at reading a map), back up food and water, some water purification tablets, two first aid kits (one is mostly my "learn to suture" kit from amazon) etc.
Running into me is like running into a general store/surgery.
