Hi Eric
From what I gather, the base is more welcoming of tours than what is really advertised. After a lot of online searching, I was able to get a contact's name. It was a guided tour conducted by a contractor with cultural services. I am hesitant to list his contact information on a post but will be glad to PM anyone interested. It was great and I really enjoyed it. You and I have chatted a few times, and your book really lit the fire for me. Also- I had it with me while out there.
