To answer tray's Scenario. Since im cooped up i na office (of which I hate offices, too many kiss ups in that sort of job.)
I would probably fill bottles with water from the dispenser, and then make sure I plug it quickly, and take it. Geussing there is window curtains in the main lounge, I would take it, and rip part of it, and make a small sack. Then, I would go to the fridge, and take anything that won't rot for a few days (preferrably something like Beef Jerky, or Raisins, peanuts, Bread, ect.)
And Place the food, and water bottles in the ripped curtain, and tie it to my pants.Then I would take the blinds pole, the pole that holds the blinds, rip it off, and
use the pole as a weapon. Then I would get the hell out, via the Back door of the place, and then use the pole as a weapon. I would proceed away from downtown. I have probabyl enough supplies ,without weighing myself down, for at least 5 days.
If I encountered any of my co workers, Well, WHO HERE WORKED IN A OFFICE BEFORE? If you have, You probably have fantisized on how to kill them. I would probably hate them, and I would kill them normally, even if they weren't zombies, since the lot of them would be brown nosing suck ups and backstabbers.
Whatever the case, outside on the street, OPPOSITE THE STREET FROM THE GOLIATH ZOMBIES, and geussing I have no car, but rather a bike, I would probably take my bike, And ride it. (A Bicycle, not a motorbike.) I would ride it, and it is faster and less strenous then walking. That way I can get the hell out quickly, and then I'll ditch the ride once I have to leave the city.
I would probably hit a conveneince store if possible, And then see if I can just at least grab something. Sure, looter's may have ransacked the place, but they wouldn't have been able to steal every peice of food in the store, and on the plus side, I know there won't be any zombiesi n there at the moment. So I would take the food, and get out of the city when I can.
That way, I get out into the countryside, and I'll probably survive, as I can live out in the bush without no knife and just those supplies, as I've done rough camping before, and my military experncies (rough camping is essentially going out into the jungle/Forest/Mountains, And taking nothing but the clothes on your back, mabye a little bag of food, or just a knife with your clothes, and trying to survive)
And in that way, I'll probably live, considering That pole can act as a Tent post when I put leaves and such or whatever I find to serve as a tent. That way I can survive out in the bush, and set traps for a bit. And zombies will have a tough tiem travelling through there, since their sense of smell will be confused by so many tree's, and wildlife, and they won't be able to see or hear well eithier due to wildlife. But now my problem would not jsut be zombies(guessing this is in North America, not my home of Dominican) There would be Bears, Wolves, and so on, but of which I could keep at bay with the pole.
Thats how I would survive. You didn't specify if it was in a tropical enviroment, or Mountain range or forest type of enviroment (besides the urban city)
But thats my plan.
