Hey /out/, this might be an interesting thread.

Lets have some fun, and theorize what would make a good shelter. So, war happened, your city is besieged/air raided, and you probably do not want to stay there, have to kill people, scavenge like a savage, and eat your fellow men due to shortages, or get badly hurt by.. stuff, its war. Also, international peace keeping forces are expressing deep concern, but not much of anything else.
