...of the Mayans, those folks whose "Long Count" calendar reaches its end this Friday, folks aren't all that particularly exercised by the possibility.
The people who think something big and bad may happen on Dec. 21, 2012 can't count the Mayan Indians who live in Mexico's Yucatan Peninsula among their number. Villagers aren't paying much attention and, as the story notes, most Mayans probably never bothered much with the Long Count calendar. It was mostly the province of priests and astrologers.
The story notes a resort which is issuing million-dollar certificates that can be cashed if the world indeed does end, if you show up at the resort following said end. If you buy one and should have the chance to collect, I would suggest small denominations. You'll probably need the kindling, and the idea that money would be worth anything after civilization collapses is kind of a silly one.
