Personally, I'm sticking with my plan to have an "End of the World" party on December 21 2012. Not because I believe that date is significant in any way shape or form, but because it falls on a Friday, and will be an excellent excuse for a party, some "end of the world" movies, and a nice smoke afterward.
Still, I may light one up on May 21 to celebrate the great anticlimax. And if this "blind squirrel" happens to be right, I'll be too busy enjoying the grand tour of heaven to worry about being upset.
