Southeast of Powder Ganger Camp West, down in a radioactive puddle with part of a bus, a burnt out car and large stack of radioactive barrels (+2-3 rads per second throughout most of the area with little to no protection). Follow the road south past the camp to the first billboard on the left (corvega billboard, the back of it will be facing the player), turn left into a small ditch that leads right into the puddle.
Nellis Air Force Base, Nellis Boomer Museum, on Pete's bed (with Patriot's Cookbook Tales of Chivalrie on the shelf above).
Crimson Caravan Company, Caravaneer Barracks, on a desk.
Underneath a few books on a table at the Recreation Office at Bitter Springs Recreation Area.
Where the player encounters Violet, it is in a wooden box on it's side in the tower over the campers. The box is on a metal shelf.
Camp McCarran, located inside one of the tents underneath a bunk bed along with several other magazines (from the middle doors into the terminal building head north, it is the second tent on the left).
