Harold Camping says the end of the world will happen on May 21, 2011.?

If you don't know who HC is, look him up on you tube along with the date. He is a preacher for 50 years and says the 'rapture' will happen on 5-21-11 (which is when all the saved people go to heaven) and the actual last day for the earth will be Oct 21, 2011. So basically all the billions of unsaved people will be left to suffer and die for several months of judgment. Any thoughts on this?
