All stocked up on food supplies, water, and ammunition.
I wasn't one of the people freaking out about the Y2k bug, but I've always got a slight creeping fear that the conspiracy nuts are just bad at math.
Then again, if the end of the world happens in a blink, then stocking up on supplies was a very foolish act.
Either way, come oblivion or another year, I just hope I'm happy.
