Before I start, I would like to say that I actually can do everything that I am saying.
I would barricade from both inside and outside. On the outside, I would put my tractor, my trailers, benches and metal fencing. I would park my 2 SUVs at strategic locations to prevent zombie entry. Windows will be boarded up and covered with tarp, blankets and towels (It's better if they don't know the windows are a way in). If time allows, I would board up doors as well.
On the inside, I would start by barricading all entries. In the laundry room I would move the washer and drier in front of the door. In the basement(after removing any needed items) I would move the massive entertainment center in front of the door. Then I would chainsaw the stairs. In the living room I would move a couch, a huge chair and the entertainment center in front of the doors. After retrieving any needed items, I go upstairs and chainsaw the staircase.
Upstairs I will have with me weapons and a ladder. Firearms include 12 gauge pump shotgun, 20 gauge double barrel, 30-06 rifle, .270 rifle, .32 ACP pistol, .22 pistol and a .22 rifle. I will also have several heavy items, a baseball bat, an axe, a sledgehammer, a shovel, the chainsaw, lawn mower and several cans of gasoline. I will have a ladder to navigate the house, as I am confident that the combination of my barricades, my weapons and my location (the middle of nowhere in an extrememly low populated town) will mean very little to no zombies.
That entertained me for awhile.
