I read things about what a person should have in barter currency in a major catastrophe. US dollars might be worth nothing. Some say gold or silver because it will never lose value. But does it make sense to barter an ounce of gold for a loaf of bread? And if food is very scarce, what would you do with an ounce or a pound of gold? I think that having a few (or several) cases of whiskey might be better for bartering. Beer would be good but has a short shelf life. Or maybe 6 months of MRE (emergency meals) or 100 # of rice to use/barter. In discussing this with a friend, he thought that maybe a handgun and a box of bullets would be the most effective to acquire food/critical supplies. ;-)
Just kidding....
