John's Treasure Box

 is an ammo box in the North West part of the Scrapyard, in a burnt out bus near a red container (see location image on this page). It contains:
 * Grognak the Barbarian,
 * U.S. Army: 30 Handy Flamethrower Recipes and
 * Guns and Bullets.

It can be unlocked using John's Key, which is on a random encounter: Wastelander being attacked by three dogs. The Wastelander will also have a note describing where to find the box.


 * The encounter can be anywhere in the game where you can have a random encounter. You might also just find the corpse of the Wastelander, when the dogs have run off or disappeared. Note that although it is possible to save the Wastelander, he does not give you anything special and will just try to get you to go away if you talk to him, making this one of the few random encounters in the game in which you actually want the person who is being killed to die.

Note that this box always exists in the game. You do not need to have the random encounter in order to get the box to appear. The box can also be picked, it does not require the key; it is a Hard lock.
