Residential District

The Residential District is a location in the Sierra Madre Villa found in the add-on Dead Money. The entire area is blanketed by The Cloud and has several lethal pockets of concentrated cloud. Dean Domino has laid out numerous traps, and some ghost people stalk the area.

Background
Before the Great War, the Residential District was a place for the casino's high rollers and entertainers to enjoy the outdoors of the Villa in seclusion.

Notable loot

 * 7 of Hearts on one of the tables in the room accessed by crossing the plank on top of the staircase you see as soon as you enter the district.
 * Meeting People across the alley from the Vending machine
 * Today's Physician in the same room with a Dean's Secret Stash on a table between the stove and refrigerator.
 * Duck and Cover! underneath the bed in Dean Domino's room.
 * Programmer's Digest on a shelf with some broken terminals on top of it. This room is located in the easternmost section of the map, upstairs beyond the poisonous courtyard.
 * Ace of Diamonds Sierra Madre Playing card in a corner by a bench just to the south of the Vending Machine. A skill magazine is also located in the garbage can southeast of the same vending machine.

Bugs

 * Duck and Cover! is stuck underneath the bed in the same room where you first meet Dean Domino. There is a glitch in the game script that causes the book to fall through the bed's surface to an area underneath the bed where no items were meant to go.
 * You should and will make several saves while obtaining the Duck and Cover! skill book to ensure that you don't push it off the map and loose it forever. Make sure to get Dean Domino out of the upstairs after talking to him otherwise you will both die. Now the directions you observe here are from the orientation facing the bed from on top of the three suitcases in the room. Throw a grenade so it drops into the nook on the left side of the bed. To prevent death I recommend that you throw the grenade from the right side and then go around the small corner of the wall(don't forget to save before doing this). If done correctly the grenade should push the book far enough to be visible when you round the corner, however it is still stuck behind the force field on the right side. Now place as many spears as possible through the glitched area on the center of the bed near the headboard, they should drop through the bed and help push the book out of the invisible force field at the edge of the bed. Place at least 7 frag mines in the nook along the left side of the bed. This can be triggered by either a grenade or a C-4 Charge, I prefer C-4. There is a dispenser nearby so if you the have demolition charge recipe you can easily acquire enough for the spears to force the book out. Make sure to save since this can fail, when detonated you'll see spears fly and first check the bed to be sure it's not still there. It can end up anywhere in the room so turn on your light so you can look carefully. This video helped me figure it out.
 * Apparently there is another and much easier way to get the Duck and Cover! book involving putting lots of explosives on the left side of the bed as so demonstrated.
