Sorry, but I have to laugh at this a little. The Archives provide a legitimate academic research service. Anyone can actually go there, and get in for free. True, you won't get a "tour" per se (though I've found Dave to be remarkably accomodating), and you can't just show up at the studios and say "let me in". (Like any modern corporate headquarters, you have to be checked through security and issued a visitor's pass.) You will need a reason to go and arrange an appointment, but the reason could be (as it was on my first visit) your high-school history project. I'm assuming Kevin and John were being hyperbolic, but if nobody was allowed in, it would sort of defeat the purpose of having the Archives in the first place.
