Defend or die
for a zombie invasion, you will likely require adequate shelter. not only from the elements, but the hordes of undead. so you should have some basic tools and supplies stocked up or used ahead of the zombie invasion to set up a barricade.
Things that will do:
-a simple chain link fence
-a horse fence wit extra lumber for reinforcement and chicken wire
-concrete wall
The above covering most or all of your property.
supplies to build sufficient barricades:
-hammer
-drill
-nails
-lumber
-chicken wire
-metal sheets
-concrete
-cinder blocks
-shovels/augers/picks
you want your barricade about 8-10 feet high at least. i suggest digging a trench or several holes in the ground around your property. brace the lumber upright in those holes or the trench and fill with concrete. when concrete has set, place more planks horizontally across the posts. between each horizontal beam, there should be cinder blocks (your choice how many)once you've layered planks and cinder blocks all the way up the posts,fill the cinder blocks with concrete. bolt the metal sheets into the outside of the wall, then the inside. then fill the space between the metal with more concrete.
*note: holes/trench should be at least 4 feet deep, and wall should have reinforcements.
