JP Stash Note

 is an unmarked Fallout 3 quest.

It is triggered by the Hidden Stash Note holodisk found in the Sewer by some skeletons. It indicates a location where you can find explosives, Microfusion Cells, and a Tumblers Today book hidden beneath some debris.

The note references "JP" and a different, unlocated stash. Whether these are fluff or a reference to an actual in-game NPC (Junders Plunkett?) is currently unknown.
