Grant: I have considered the pepper spray but I cops in NJ will give you a hard time if you have it. I don't thinks it illegal but...
I have some hard candy in the backpack but I need to add an energy bar. Good suggestion.

RAS: I could easily be a knife nut but I work hard on controlling myself. I have shied away from a pry bar because of weight issues. If I could find a reasonable (cost) one made out of titanium I would consider it. My FAK started as a Red Cross belt kit to which I added. It includes: breathing barrier, 2 pairs of gloves, a selection of bandages in different sizes, Some gauze pads, 2 roller guaze, a couple of antibiotic ointment wipes, and alcohol prep pads. It used to have some sting-eze but they expired and I haven't replaced them yet.

Kc2ixe: Interesting idea about the hand towel. Thank you.
