Get your stash of bottled water: According to the followers of radio preacher Harold Camping, Judgment Day is coming tomorrow. Camping et al. believe that 200 million people will be "raptured" on May 21, whereas the rest of humankind—and the world—will be destroyed. While Camping has his partisans, there's no reason to put all of our eggs in one apocalyptic basket. As part of Josh Levin's 2009 "End of America" series, Slatereaders picked from 144 possible scenarios—loose nukes, alien species, a new ice age, and many, many more—in the "Choose Your Own Apocalypse" game.
