Capitol Post building
The office section of Capitol Post contains a small reception area, and a back room with terminals containing stories published in the pre-war Capitol post, and a printing room in the basement. One of the terminals is rigged (first terminal on the right) and the reception terminal is linked to a sometimes hard to discern safe, situated in the left panel of the receptionist desk (when facing the terminal).
There is a locked door that leads to the terminals, but the player can simply walk around it where there is a giant hole in the wall, leaving hardly any "wall" at all. The only enemies found in the office are several radroaches.
The Capitol Post building appears only in Fallout 3.
