The minute the balloon goes up and things start going wild, I'm gonna take a trip to my nearest land rover dealership; which is about 4 miles away.
Using the landie, i would keep on the move and gather enough supplies from the surrounding area to stay alive for a week or so, and them move on the immigration centre. I worked there for nearly 5 years and know enough about the place to be able to get in with only a ladder! Or there would be someone i know already there anyway.
The gates around all the compounds would be reinforced, starting with the main entrance and main gate as in the pic.
There is enough food in the place to feed 200 people for a week, so i wouldn't be worried about running out of food to begin with.
While carrying out the vital alterations to the fences and the building its self, anyone who wanted to come in would be welcome. But they would have to be vetted first. With exception to people i know, and those who had worked there before of course!
Before entry all persons would need to meet a few criteria:

• Be subject to strict strip search

We don't want any junkies/undesirables now do we. Plus, to checking for bites and infection.

• They must accept that anything they bring into the area, is now everyones! All is shared!
• Everybody works. From cleaning to building defenses. No work, no shelter!
• There are rules and anyone who doesn't agree with them can bugger off.

Crime will not be tolerated
Lee in Ireland makes a really good point about survivors. I f they were strong enough to survive the initial outbreak, they are strong enough to be a hazard to me! much respect to lee.
Thats basically it. Use the landie to get more vans for other people to use. Then go out on raiding parties to local areas to get food, water, fuel, supplies like metal and wood, and of course porn!
We would use CB or two ways for coms, and to try to contact other colonies/survivor groups as well. Like noel, in wales. (good thinking on the CB taff)
My handle is 'The welsh wizard'.
We would search for supplies daily in different areas around the facility, using a different team or teams every day, with different objectives:

• 1: Food and water
• 2: Medical supplies
• 3: Fuel
• 4: specifics (car parts, building materials, wood to burn, etc)
  

A steel wall would be put up around the fences; not just to reinforce, but to keep Z from seeing people inside the compound.
The facility would be run as a democracy, but there would be internal law keepers, and ultimately a facility manager.
A number limit of 200 in the building its self, and another 100 or so in a tent city in the grounds.

BUT!!!!!!!!! All that goes out the window if I'm on my own! All the above is very good, but i may not meet anyone. I could be completely on my own. in which case all the same will happen, but alot slower!

All in all, stay alive. Help as many people as we can without overloading.
I will add more to this page as i think of it.
FEEL FREE TO CHANGE MY GRAMMAR AND SPELLING, ITS AWFUL.

Addition:
I would make a 'fire break' around the facility. Clear all trees and vegetation up to 100 yards.
There is afew reasons for this:

• You've got yourself a kill zone (handy later when you have firearms)

• To stop Z's climbing trees, or building basic ladders/climbing aids. (dependent on intelligence levels)

• The area can be used as a burning area; Coat it with paraffin, or anything that will burn that isn't fuel for vehicles. I'd

also make poor mans napalm, so the burning material will stick to the z's.

Addition:

No other reason for this gun to be here. I just like them!

Addition:
In the said fire break; i would use fishing line and tin cans to make a basic intruder alarm.
id use these because they require no power, and will probably be easy to get hold of.
Id try to get some barbed wire as well. This would aid in the slowing down process, and make them an easier target
