I drove off the NCR ranger and returned to the Hidden Valley Bunker and then came out again after getting the quest to find the other Brotherhood patrols. It wasn't until then that I realized that I still didn't have my stuff. From what I've read online, it's supposed to be in a box or weapon case near the crates in the first room down the stairs where the intercom is. I also checked the room with the barricades in front of the door to the lower level and the entry room beside Ramos. Is there any hope of recovering my stuff? I don't have a good save game to go back to.

Dunno. I always just have Veronica open the door. No one takes my stuff.
