Doomsday prediction has believers preparing, skeptics scoffing.
You've probably seen the billboards, the buses or even the full page ad in USA Today.
Followers of Christian broadcaster Harold Camping are warning the end of the world starts this weekend.
"May 21, 2011- exactly 7,000 years from the day of Noah's flood will be judgment day," says believer John Junstrom.
According to Camping, earthquakes will begin shaking the ground on Saturday.
Believers will ascend to Heaven in what's called "The Rapture", while everyone else will face the world's destruction over the next few months.
"We believe it 100 percent," says California Ken Ronning.
But not everyone does, including many other Christians.
Some atheists have started sites like Eternal Earth Bound pets, promising to care for Fido after The Rapture...for a fee.
In Indianapolis, Anna Reese is offering the same service on Craigslist.
"50 dollars per small dog," she says.
In Pinellas County, Florida surviving saturday could get you a deal.
"If you make it past The Rapture, you basically get a free dryer vent cleaning with any full duct cleaning that you purchase," says Christian Scheeler of AirMedics Duct & Dryer Vent Cleaning.
Camping has predicted it all before back in 1994.
He insists he has it right this time.
"It is going to happen, and so, I don't even entertain questions when they say 'Oh, what are you gonna do if it doesn't happen'," he says.
Skeptics say they're not counting down to the end of the world, but rather the "we're still here" parties planned around the country.
People have been predicting the end of the world for eons.
Many have been asking about December 21, 2012, when the Mayans predicted the end of days, so if we survive this one there is another Doomsday about a year and a half away.
