Strategic Nuclear Moose

 is an unmarked quest in Fallout: New Vegas. There is no XP or Karma to be earned.

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 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.
