The Coming of the Rapture?

A man named Harold Camper who I believe is a radio show host who is very religious claims to have counted out specific dates and times in the bible that can predict "Judgment Day." Unfortunately for people that believe this old mad man he has already predicted this before in September of 1994 and claims that it didn't happen because his "calculations were wrong," who's to say that he's wrong once again? People like him who make such broad statements should not be listened to.
