I Want a Bomb Shelter

Hear me out here: I'm not one of those weirdos who think that the world's gonna end any day, or even one of those weirdos who think that nuclear proliferation is bad (we can talk about that later). I just think that it would be a cool place to hang out, like a really deep basement/rec room with integrated cooking and bathroom facilities. Maybe I really just want a full-sized basement with a kitchen and bathroom attached...
