A few years back a convoy of Humvee's took a right off of AZ RT89A took off north just west of Sedona and the Boynton Canyon Rd. In this area there is a place called Bradford Ranch ...the convoy passed it and continued north never to be seen again as somewhere in that area is a underground entrance and road that takes you right under the the mountains...north on loy butte rd ... A cleaning staff member has said there is a VIP entrance as well within the Enchantment Resort which is in Boynton Canyon it's self...Socorro NM has been mentioned near the VLA and talk of something in the fours corners area and the Grand Canyon it's self. When you consider the Air Force bought to boring tunnelers they went underground 20+ years ago never to be seen again. I expect the network is bigger then many thought possible.
