Georgetown

Georgetown is a Washington, D.C. neighborhood located in the northern part of the city.

Location
Georgetown must be entered through the Metro system, but it is well connected. Easiest may be to enter it via the Tepid Sewer. (And it is also the most probable way you came to Georgetown, since you probably were hunting Molerats there.)

Radiation King
In the northwestern area is a Radiation King store, with a Scavenger.

Cornucopia Fresh Groceries
Next to the Radiation King is the Cornucopia Fresh Groceries, and next to that a Pulowski Preservation Shelter with a Nuka-Cola Quantum.

McClellan Family Townhome
Just about in the middle between Georgetown North and South you will find the McClellan Family Townhome. Inside, there is a rather moody Mr. Handy robot you can play around with using a nearby unprotected terminal. Modes of operation include reading the children somewhat interesting bedtime stories, walking the dog, grocery shopping and home security. Using these modes you can enlist the robot's help in fighting the many super mutants in the area.
 * Skill Book: Lying, Congressional Style through door straight ahead on table in the townhome.

Sniper post
In a broken building in the center, quite close to and opposite to a balcony with a Super Mutant Master with a Missile Launcher, is a Raider corpse with a Sniper Rifle and ammunition for it.

La Maison Beauregard
In the southern area resides La Maison Beauregard.

Notable Loot
