imageThey’re wearing sweatshirts and other clothing announcing the "Awesome News," that Judgment Day is coming on May 21. On that day, people who will be saved will be raptured up to heaven. The rest will endure exactly 153 days of death and horror before the world ends on October 21. That message is splashed across their five sleek, vinyl-wrapped RVs, bearing this promise: "The Bible guarantees it!"

Belief is a strange phenomenon sometimes.
