Where to go?
By the book:
Protection, first aid, aids, water, food. PFAWF - Priority First Actions When Foundered. That's from survival training like 30 years ago. And I still remember it.

So I thought that my estate (which is a bit Alexandria-like, but with a prebuilt 6' brick wall) would be great. Block off the vehicle entry points. It's arranged as a D in a larger D so you can have lines of defence and fall back.

Thought that for years, ever since TWD has been on. But just lately I have had a great revelation....

Bunnings Warehouse!! (that's sort of like Home Depot for you USA peeps). Why?

Well, the pros:
Large area inside a precast concrete box, impervious to small arms fire.
Limited entry points (easy to defend)
No windows in the walls but lots of natural light due to roof design.
Lots of height (high ground always preferred in battle)
Huge amount of construction supplies to build fortifications, living areas, workshops, kitchens, showers, the works.
Large car parks surround the site so great sight lines.
A handy 20,000 gallon water tank for fire fighting requirements.
Lots of gas (that's propane, not vehicle fuel).
Generators on site.
Normally in industrial areas, so good pickings from surrounding district.

Cons:
Not much in the way of food (have to BYO).
No bedding. Unless there's a Captain Snooze outlet down the road.
They dont sell HiFi, so if you want a big home theatre, you'll have to hit a different outlet (maybe Harvey Norman or Domayne, they have bedding too. And lounges.). I mean, just coz it's the Zombie Apocalypse, you don't have to live like Fred Flintstone, right?
