Meanwhile, not quite Doomsday but more like Pain-In-The-Neck Day.
The basic idea, cover your back in case the WWW goes FUBAR.
- Keep some (not a LOT of) cash stashed/handy. Again, not a lot of cash. Just enough to get by while things reset. We're talking some $10's and $20 in your wallet, don't be the guy who tries to buy a pack of gum with a $100 bill. A couple of hundred bucks in 10's and 20's is fine.
- Keep any prescriptions on hand that you need.
- Think about how to communicate and travel if needed.
-Buy one or two shipping containers of toilet paper and LYSOL because OH MY GOD, YOU'RE GOING TO NEED IT!!!!

Kidding, don't panic. Just be ready in case certain world powers decide to act like angry three year old's.
EDIT- I almost skipped the important part.
-Spread the word. If you're the
only guy in town who got their #### in one sock before the mayhem happened, how is that helping
you??
