I know this is an old thread but I just joined literally so I can try to help clarify some things...
I was at the Roaring Creek Earth Station today and took several photos. The roads leading to it are pretty desolate but there are residential houses nearby. Not much activity happening within the gates. Front entrance's "guard shack" was empty and adorned an AT&T sign. A recent one at that (newer logo). The fences contain barbed wire, but that's about the security they have. There are no towers of any kind, it's not like Area 51 or anything. It was incredible to see the dishes in person though.
