I hate it. Every time I buy into one of these here doomsday predictions I get all hot and bothered, I go out, rent trucks, some storage space - cause you know it's going to be a once-in-a-lifetime chance to loot. And then...nothing. I think they ought to be required to turn everything in ahead of time. You know, put their money were their mouth is.
But hey, at some point the law of averages - and entropy - is going to cause one of them to come true.
