Definitely a good investment.
Arable land, some food stores to get you by when the crops are lean, and some firearms to protect it all.
one of my relatives is a dairy farmer...I was thinking of finding farmland near where he ultimately decides to set up shop and then rent it to him to pay the taxes until I’m ready to use it...
along those lines, fertilizer may also be a good investment if food is expected to be at a premium...
