So far most of my BOB is theoretical...I know...get it put together!

One thing I carry in my wallet, and will go in every BOB/ditch bag is a couple of family pictures. As has been said before, there's nothing like a good reminder of what you may be surviving for. That is a morale booster for me.

And items like folks have mentioned are all part of the MENTAL part of survival, which has a profound impact on the PHYSICAL part.

With small, relatively lightweight mental distractions...well it just makes sense to pack these things. Now if you're really into bowling...

But the body follows where the mind leads, so never underestimate the importance of mental survival/comfort.

BTW...LOVED the comment about carrying a deck of cards, so someone will happen along to tell you where to play your next Solitaire card!
