I have made some preparations. I chose a place to live that is nestled in a canyon with two ways in and out, protected by sheer cliffs that cannot be scaled and is in a line of abandoned houses, fresh water from a creek, an open woodline for hunting. A small plot of land big enough to grow enough food to support myself, and a defensible armory less than a mile away.
Other preparations such as heavy weaponry
Some rudimentary supplies such as crank powered radio/flashlights, batteries, shells, extra blankets, two dozen empty water jugs, DC to AC power inverters, medical textbooks, engineering textbooks, Extensive first aid kit and other items.
However there is still plenty of prep work to do like building water filtration system, Distillery, Faraday cages, General tools like wood axe, shovels, post diggers, Tarps, nails, screws, etc stockpile nonperishable foods and other preparations, but will be making those preps in about two more weeks, and most importantly I start EMT training in May.
So yeah a few preparations have been made, but you can never be prepared enough.
