We’ve been growing our own vegetables and meat now for years. Plus I hunt and fish. My wife has taken up canning again and I am building a root cellar. We are also raising chickens for eggs. Last year I installed a mini hydro-electric turbine in the stream that runs behind my barn. If worse comes to worse we’ll be OK, but I’m gonna have to defend it all.
Yup, that’s gonna be the major issue alright.
Those that have prepared and/or can “live off the land” and their own ingenuity will have defend themselves and what is theirs from those that would take it by force.
Thus it has always been.
Team up with like-minded people NOW so that you are prepared for the worst should it come to pass.
