So let me start of with I was a security guard at the Marine Corps Air Station Tustin in 2000, all buildings were left as is, I was on second shift so as soon as the sun started going down me and the other guard started exploring.

The helicopter hangars and two fire stations was the first, then all the other buildings like one in the south east part of the base. It had a large vault 15 x 15 with the radioactive sign on the door and that door was about a meter thick, at the time all I had was a sony digital mavica camera that used a flopy disk. I lost most all the photos I took but here's what I could recover.
