(lighthearted - I hope this isn't a real risk!)
I've been thinking about where I'd rather be if there was a significant chance that the SHTF. Say if there were riots because of no deal, would you prefer to be in a city, with more people (and rioting) happening around you, but in a defensible flat, within walking distance to things like hospitals and places to get food, or in a more rural location but anything you might need would require driving? At some point potentially your storecupboard might run out, and your transport choices would be more limited.
Assuming you don't have a moated castle to hide out in, would you rather take your chances in a city, or the country?
