It is 17 and two-thirds miles as the crow flies from my bedroom to Burrow Mump, and just under 21 miles by road. Whilst I would usually advocate not driving, I live one row of houses from the countryside, and only on the edge of a small town (estimated under 10,000 population).
A panoramic view. *warning Semi-long load*- It's also the worst side, the other side of the church is just farmful to the horizon, a small stream and a clmup of trees, hanging over a cliff at the bottom of which is a mechanics and a couple of houses.

The roads on the way there pass through two even smaller towns (avoidable by darting down farm tracks) a village and that's pretty much it. Burrow Mump is a National Trust property, meaning free access for anyone; but because of the sparsity of the population (check the wikipedia pictures. There's a pub, a few houses and that's it) this shouldn't be a problem. At the time of Zombpocalypse discovery (either announcement on the news or me getting incredibly suspicious).

I will grab my brother's Air Rifle and all the ammo we have about the house (several thousand pellets at least). I will also grab the pump for it (the wonders of air powered weaponry, infinite shots if we get 20 mins for him to pump it back up), a few spare clothes, (for varying weathers), all the tinned food from the house, my brother's knives, and all the bottles I can find (emptied and refilled with water), a saw or two, a chisel, whatever's left in the petrol can in the shed, all the seeds in the shed, my tent, my brother's tent, all the matches and lighters from in the house (smoking parent=bonus), shoe polish (it says to on the YZP wiki. Could someone explain why it'd help?), basic first aid kit, all the salt, all the containers, pots and pans I can reach, and anything else I deem useful at the time.
*edit* + Towels, pillows, hammers, OS map of the area, spade, my brother's chainsaw (if it's fixed by then), my potato plant [Seamus], spare shoes, sleeping bags, blankets, The Zombie Survival Guide [kept next to my door, just in case].

I would gather everyone who I trusted to work (most everyone) and have everyone do the above. These peope include my family (up to Grandparents- only live a couple of streets away), my friends (from a few houses down to the other side of town), their families, and anyone who shows up and listens to my insane rambling. We would then put everything in the car/cars and head off to Burrow Mump.

Now, atop this steep and difficult to climb hill, there is a ruined church. This will be the basis for a defensible building, more for ease of building (as it is already 4 strong stone walls and a small tower- all gutted inside) than for any sacreligious notions or image. To one side is a small village *edit*- about 500 people, pretty much just a pub and a few houses (check the wikipedia pictures to see how abandoned it is. They don't give a proper sense of scale though, OH LOOK! A LINK TO SOME PICS!). These will be used to begin building a semi-permanent shelter. I will begin by cutting down the trees on the lee side of the hill, as they are tall and strong, and also block a fair sized wedge of land.

Over the next few weeks, I will raid all I can from the surrounding houses (everyone who doesn't flee is welcome to join me, if they don't want to, or won't let me take their stuff, onto the next house I go) and begin to build the church into a survivable home. When the bottled water is done, there is the small stream I mentioned. I do not have any purifying tablets etc, but I would boil the water in the pans, although I do trust the stream, it's short and doesn't pass near to any sources of pollution (except sheep). These sheep would be kept on the hill (there is already a small group of sheep and goats that are), and the surrounding fields will be used for growing anything- they should already by planted (so long as the Zombpocalypse doesn't strike in Autumn or a heavy winter). Those fields that are not planted will be used to keep livestock- there's a couple of fields of sheep already, and about a half-mile down the road is a laaarge herd of cattle, who would (hopefully- my friend lives/works on a cattle-farm, but I have no experience with cows) be driven closer to the hill and kept in a nearby field. There's also an absolute ton of Rabbits in the area. I have some experience hunting rabbits, but my brother is rather good at it. I am willing and able to skin, gut and joint rabbits, and will probably be fine on bigger animals too. I don't think Cows would be very easy though...

I would never stray beyond the horizon from the tower, and would accept any incomers who would submit to a 24 hour quarantine.

I'll check this every now and again for feedback (it is now my main plan, being much more feasible than Flee to Takutea.
