I have barter items that I think might be exchanged at high value. I know prices for all kinds of things will go nuts and beyond just feeding ourselves we need to think of all those things we simple cannot do for ourselves and barter items might come in handy.
alcohol is a GREAT barter iten and med toolkit item as well...
Plus if thermonuclear war breaks out it is good to down a bottle of vodka while watching the million degree sunrise on your front porch if you happen to live near a millitary base....
