I can tell you guys a lot more, just so long as I don't mention any names
My Grandpa worked for the government for, well his whole life, then he was discharged (honorably) and now he spends his time searching for UFO's and
talking to his "buddies" he has a lot of information on these things, and he's pretty good at making sure he doesn't mention any names.
According to him, there are bases even more top secret than area 51, but they don't have names like that. One is DULCE, which many have heard of. He
says it really exists and as far as he's been told, it
is an alien base.
He also tells me about Iron Door Mine, anyone ever heard of that? If you want me to post some information on Iron Door Mine just tell me. My grandpa
and I often get into those type of conversations and he always brings up information on The Iron Door Mine.
