Oh, come on. How fun would it be in a bunker? You could run about for DAYS playing live-action Fallout, getting by on 'nuclear fallout' staples like tinned peaches and Spam. You could pretend the rest of the world was dead and forget about work, school, or social obligations. You could befriend the cockroaches, because you just know they're going to end up being the master race once we're all dead.

Underground bunker, easy.
