They run tours there.
So I got thinking about making your own Zombie Apocalypse House. One with a few tricks of its own. Here are few ideas I have collected from people.
Looks like a few planks resting against the back fence but in fact it is a ramp into the yard next door. Good for a fast get away, especially as zombies don't have a great sense of balance and will find it hard to follow. Also great for using the neighbour's pool when they are on holiday.
This fence backs onto a reserve and is fairly well hidden by the shrubby. There is a gate in that ramshackle fence and judging from the slightly worn trail it gets used occasionally. Obviously a nice escape route when the religious fanatics come door knocking.
If you have the cash to flash and the room, create a hidden alleyway beside your property by installing a fake inner fence. I have seen this used on several properties.
Providing it is not raining, drains can be a wonderful resource for those plagued by an abundance of zombies. It is also cheaper than digging your own bunker. Even if you can't fit your family in there you can use it to cache your survival supplies. Or at least keep your beer cool.
Bite off more than you can chew.
