Liquor, spices and seasonings are good for barter should the need arise. Staples to have on had in quantity:
1. water or the means of purifying water
2. dried beans
3. dried rice
4. dried or freeze dried meats
5. canned goods
6. powdered milk (good or all manner of baking,cooking, drinking)
7. powdered drink mixes and, if you like tea, tea bags
8. smoked meats will keep for a LONG time providing you have a place to store them away from rodents and insects
9. canned goods, especially fruits and vegatables
Don't forget other stapes that could become hard to come by in the event that international trading should become a problem:
razor blades
sewing needles and thread
Standard staples that a lot of folks don't think to stock up on:
1. Toilet paper
2.. Paper towels
3. Paper plates (if water becomes a problem, I wouldn't want to have to use what little I may have to wash dishes!)
4. personal care products like soap, shampoo, deoderant, etc.
5. batteries (must be rotated to keep fresh ones)
6. first-aid products like peroxide, alcohol, bandaids, pain killers, spray disinfectants, gauze and tape.
Think of the things you use every day and expand your list accordingly.
Oh! And last but CERTAINLY not least:
The means to protect it all!
