Planning a trip to Raven Rock

I am going to drive there sometime this week since I recently noticed it is only an hour from me. Anyone been there before? From some of th pics it does not seem to be very well guarded at all. Is there anything there even worth checking out?

It is well guarded by Army MP's out of Ft. Dietrich, MD and completely fenced in. There's absolutely nothing interesting or conspiracy related there, especially nothing worth getting in trouble for. There's a good overlay of Site R for Google Earth that I found, it's accurate as well. The facility is just a run of the mill refuge for policy makers and various executive branch members in case of an emergency.
