It occured to me that surviving in the city wouldnt be such a bad idea (depending on the circumstances). Youve got access to food for a fair while, youve got established shelter with heat, electricity, and water (assuming its still working; unlikely but possible) utensils of all kinds, you dont have to worry about the weight of a pack or anything, and a home could easily be fortified for defence; and most houses have a fire extinguisher in case some amateur arsenist comes knocking. Youd also be with your family; Your surrounded by neighbors and friends with the same kind of preparations (most families have at least earthquake supplies). You'd have your choice of whatever weapons you have on hand, too; no need for the "do all weapon and ammo" that one requires in a bugout situation. Of course, this isnt to say that it would be a better idea than heading for the hills; just an interesting alternative. Largely depends on the scenario.
