A lot of my friends can't even load a gun it's pathetic. A lot of Americans will die quickly if things get bad. Having a enough food for a couple of months helps me sleep better at night. You can buy rice and beans for pretty cheap. Get some plastic buckets from the local bakers they will give them to you for free a lot of times. Put a couple of oxygen absorbers in the buckets and you will have a cheap food supply that can come in real handy.
I'm just gonna set up a place in a remote forest were I can live off the land. Enough animals to hunt and enough plants to pick. Also stock up on food. Someday live there full time with animals and crops. When I go back to US i'm gonna get started on that.
Being able to live off the land with minimum need for anything else is essential. Urban and suburban people will be fucked, they'll be looting the grocery stores and killing each other really quick.
Rural people with gardens and animals and stock piles of food and supplies will be in much better shape to survive.
