My plan is to have enough wheat to eat what I need and trade the rest for gold.
Yours is the most sensible so far. That’s the plan, for sure.
We all had better have some of everything. Gold and/or silver, food stores, and other basic needs. When and if the SHTF your stores will last only so long. If you don’t have something to barter then you’ll be up a creek. It’s not a bad idea to start learning how to grow some of your own “wheat” for when it gets hard to find, no matter how much AG or AU you have. And, don’t forget the Pb.
