Strategic Nuclear Moose

 is an unmarked quest in Fallout: New Vegas. There is no XP or Karma to be earned, aside from possibly picking the locks on the cellar door and the gun cabinet.

Walkthrough
If you're thirsty, Brewer's Beer Bootlegging is a good place to get some free booze. With a Lockpick skill of 50 the player can open the cellar door and find Gourd's secret distillery there. (There is a key to this door in the main room, it is located to the left of the locked door on top of the bookshelf; along with a Sunset Sarsaparilla Star bottle cap.)

A sign says: "Strategic Nuclear Moose: And God said, let them have beer"

Locate all beer bottles, there are enough to become drunk. Don't forget the Big Book of Science on your way out!

There is a key under the Big Book of Science. This key goes to a gun cabinet against the same wall as the Tactical Moose sign but in the large room. The gun cabinet should hold an assortment of loot including a Gauss Rifle (but only at higher levels).

Behind the scenes

 * "Strategic Nuclear Moose" is likely a reference to the real life beer "Tactical Nuclear Penguin" made by a Company called Brew Dog.
