Salt. I read that a good supply of salt will be worth gold. Don’t know if it is true though.
Wars have been fought over salt.
salt preserves and is good for wounds. among other things.
When Mayor Bloomberg started talking about banning salt, I went out and bought a whole bunch of all different kinds of salt. Sugar and Vinegar too.
I need to buy some more, but I need to get a space fixed up to store it all. Salt, Sugar, and vinegar are very important to some of the food preservation techniques.
Besides, I figure the food police are going to start rationing sugar and salt for the good of the children - doncha know?
