Not only is that fictitious, but ridiculous. There are 'hidden' budgets in the US, however these are mostly related to DARPA and other R&D operations where the true nature of what is being researched must be kept secret.
I meant it as a joke, I know that isn't true but I thought it would fit with the topic.
Area 51 falls under the "there's probably something sneaky there, but to be honest I don't want to know" category for me. If they've been keeping that place a secret for >50 years, they probably have a **** good reason.
Oh my gosh, this question has been going on for ages (just kidding) . But from what I've read and heard, I'm convinced that there is something fishy going on there...Yeah, I don't think I should have said that information either... Crap! *Dies*
