Denver does have underground bunkers, whatever you call them. Its been going around the traps for quite a few years now. Denver is a big airport, will take the biggest planes and is easy for Airforce one to get in and out of. Considering that most of the coastal areas of New Jersey and parts of New York are still without power or any services I would not be surprised that some very important people are headed there.
All so take the warning people, do NOT think that our government would help us in a disaster, they will not. just like Catrina and now with Sandy, millions of Americans have found that out for themselves. We will not be any different here. Get your wind up torches and radios, have a stock pile of food and water and things you might need for an emergency and don't tell anyone your doing it or you might wake up face to face with looters!
