Shelter (Fallout 3)

Location
The Shelter is a small area unmarked on the Pip-Boy world map. It is located South of the Chryslus Building, and East of Farragut West Metro Station. The entrance is a door underneath an intact bridge. If you start at the entrance to the Chryslus Building, head South to the second semi-intact road (it should have concrete dividers in the middle). Coming from Farragut, head around NNW up the slope to the first road (there is probably a group of three Raiders just to the West that you may have to deal with. Follow that road East (if you wind up seeing an intact bridge with two statues of three Valkyrie / winged-women, you're on the road to the North and it's safest with folowers to backtrack West to get to the next road to the South).  There's a blue and yellow truck in the East bound lanes with 3 Ammunition Boxes.  The door to the Shelter is under the North side of the bridge just past the truck.  You may see a fire ahead on the road, this is a burning pile of tires at a small fortified Super Mutant camp (in my case populated by a Super Mutant Master with a Minigun, a Super Mutant Brute, and a Centaur). Approaching the Super Mutant camp may trigger an Enclave Vertibird dropoff after The Waters of Life Quest, 2 Enclave soldiers and a sentry bot are usually dropped off on top of the bridge.

Interior
Inside the shelter is a Feral Ghoul and what appears to be the remains of a Jet-making lab. Medical supplies are stuck into the face of a Damaged Garden Gnome to form an effigy of the Statue of Liberty, and just inside the door is a tower with a book supported by pencils with a Coffee Mug, Nuka-Cola and a Tin Can balanced above it, touching it topples it. A trail of plungers go from the floor, up the wall, and onto part of the ceiling, accompanied by bloody hand prints. The skeleton of the would-be wall-crawler lies on the floor under the last plunger on the ceiling. A nearby mannequin brandishes more plungers and even wears one as a hat. There are about 48 plungers in the room, including one on the ceiling, which when shot oddly falls over upwards onto the ceiling. There is a man of plungers on the gurney with a Metal Helmet for a head and a knife in his crotch. The real mystery, however, is how even a Jet-fueled madman could get such a large stone bust into the entry hallway.

Also known as the "Plunger Room of Death" this is obviously an Easter Egg area like Gold Ribbon Grocers or the Shrine to Abraham Lincoln in the basement of Arlington House.

Exterior
There is a small Talon Company outpost situated to the west around an abandoned truck and usually is comprised of a single Talon Merc and a Sentry bot. Combined with the presence of a Super Mutant Camp to the East and an Enclave drop off point on the bridge At higher levels (especially with the Broken Steel DLC pack) the area can be the center of some bizarre and complex firefights; I encountered a battle between Talon Mercs, Super Mutants ,and the Enclave with some Hunters trying to kill some Wastelanders in the background. There was a grand total of 3 Enclave Soldiers (all wearing Hellfire Armor and one with a Heavy Incinerator) with 1 Sentry Bot, 2 Super Mutant Overlords, 1 Master and 1 Centaur not to mention the Talon Merc and his Sentry Bot and the Hunters on the Ledge above the Mutant Camp. A second Vertibird showed up after all the others were dead and an Albino Radscorpion spawned near the Hunters corpses. There was plenty of loot after the battle was over.

Behind the scenes
The Plunger room is an exact cut/paste of a room in Taft Tunnel (second part, right after the part where the two Ghouls have killed an Enclave Soldier), down to the rare "IV Stands"
