At some point in the future men and women of all stripes, but mostly the elites and extremely rich, will flee to the mountains and the caves, hiding under rocks, in bunkers, dumbs (deep underground military base), inside of mountains (NORAD) and anywhere they can find to hide from God and His anger, fury, and fiery judgment.  Interestingly enough, this has already begun, although it won't see its final fulfillment until the Tribulation.
