STALKER style stashes

[Geoarrge]

I imagine it could work like this: you would be able to find or purchase stash notes which function like treasure maps, except instead of pointing to a buried treasure they would generate a backpack or duffel bag somewhere. There could be groups of sleepers or booby traps guarding the container.  The note will describe the contents of the stash in detail (e.g. "100 9mm rounds") , or more generally ("ammo"), or not at all (wild card). 

Purchasing wild card stash notes from a trader could be a way to include a "buy unidentified items" kind of gambling mechanic.
