I believe that Area 51 is real, but, well, i really don't care less if there are alians there. Who cares? I mean, yes, perhaps the "UFO" from the Roswell Incident is there, but i just can't see it.
If, of course, there ARE aliens, then i think they are doing a mighty fine job making sure no - body else finds out about it.. -.-. Surely if there WERE alians there, someone would've leaked it, as they would probably get paid by the media. But until we find out, i'm just going to leave it and not think of Area 51.
