> If you’re two states away from where a bomb goes off, and insist on open-mouth kissing strangers as they cough on you, that’s up to you.

Which states? Two states away can be <10 miles or it can be >500, even if we ignore Alaska and Hawaii.

As to "open-mouth kissing strangers" after a nuke, that's a rational way to build the social structures that you're going to need to survive. Stand back and be the creepy guy. That difference trumps whatever "little safer" you think that you're getting.
