I always think what if zombies attack. I'd be pretty fine. barbed wire everywhere around here. if I had a few mates with me, we could go down the paddocks, two guys covering and one guy getting the wire, then all we'd have to do is walk with our supplies find a spot on one of the mountain/hills around us, wire ourselves a little hold. dig trenches, barbed wire etc and we can see over the land without worrying about zombies. then do nightly raids on houses taking supplies clothing etc needed for making scrim nets and ghillie suits. I also know how to make potassium nitrate easy enough so we could make explosives. also know how to make acetone peroxide so I could make landmines etc. except acetone peroxide is very unstable, but could be good for a last resort, also could use as a primary explosive for something like ANFO. It's all easy. for food we could last ages on killing birds and cows and horses, water we could make carbon filters to filter the water from the streems as much as we could, also boiling the water to reduce chances of malaria and waterborn deseases. medical could be boiled clothing for bandages for cuts and such. if needed bullet proof clothing could be teracota, and also could be laminated glass and polycarbinate. that could deaden the bullets, not nessarily save me from the bullet. shelter could be plant matter and a ditch. also for ammo lots of people have guns around here and all I'd need to do is raid houses again, maybe steel a angle grinder to cut into peoples gun cabinets (mine require electricty). thing is I only have one magazine for each of my weapons. that might make some trouble.
