a large enough place in the hills where it is cheap. Try to buy where you think either commuters will be wanting to go in 5 years or where nudist camps would work. Find a Mobile home at a repo auction pay a couple of thousand to haul it to your dirt. Go there on weekends and garden, build a shed slowly make improvements. On the day of the rope you can retire there fleeing the city as it burns. If that doesnt happen self sufficency growing a lot of your own grub is healthy and good for the kids.
