Me, I'd 'go bush' & live off the land (something i learned to do young when I was growing up overseas), being tied down to an area can be a disadvantage
I have an emergency bag with the usual first aid kit & supplies, 2X20L metal jerry cans for my xtrail & a pushbike(don't need petrol for a pushie ;p)
I'm by no means one of those loony 'preppers' but it never hurts to be prepared for an emergency eg. natural disaster, long term power outages etc.
One other thing & bear with me on this, one thing I've always found odd about apocalypse/zombie movies is they almost always get about in cars or on foot. Cars are a short term solution until you run out of fuel sources & being on foot takes a lot of energy & relatively short distance,
the solution: pushbikes. No need for fuel & you can cover much longer distances rather than on foot
