I must agree with Inspector: food, water, firearms, ammunition. The idea of having smaller barter items is great, and small amounts of ammo are easy to carry, easy to hide, easy to give at a good price. Those of us who can reload will be valuable, as will the reloader machine, but we will need the basic materials. Just short of the ammunition, which may be in short supply: a wrist rocket slingshot is lightweight, requires a little practice, and easier to reload: there is ammunition everywhere! Thanks for the info on Bosnia, a SHTF will probably be similar. Two things manifest when SHTF: 1) the very best of humanity rises to organize and care for others, and 2) the worst of humanity become vandals and vermin. Your best bargaining materials are not materials: it is the relationships and skills you bring to the group. I'm REAL interested in forming a network now to be ready for the future. Takers?
