OP, you're right there are issues and welcome to the new ice age, but the US gave up grain reserves in the 70's. Hasn't a thing to do with Trump. Blame Nixon. The same guy that took us entirely away from gold to fiat.

Potatoes, Jerusalem Artichokes, acorns, flush out the tanins first in a creek or even your flush toilet tank. Cattail roots...Lots of starch around. One only needs to know and look.

Also, dare I say it??? Stock up and have a plan to get someplace fairly safe.

We have livestock. Feeding them will get interesting before it really starts to hurt at the grocery store.
