There are four different bunkers in Hidden Valley. Two are empty, one has a NCR Ranger living in it, amd the other is the BoS underground fortress.
Theres four? I only found three guess I need to head back and explore.
Gee thanks you guys, now i have a bomb strapped to my neck, what is this Fable II?

Hey it could be worse. You coulda went into the valley at night with the sand storm happening only to get cut down by 3 - 4 BoS knights leaving for night patrol.
