Pennsylvania Avenue

 is immediately to the east of what once was the White House. This area is a constant battle between Brotherhood of Steel and Super Mutants.

Points of Interest

 * Scavenger in the northeast, in an underground parking garage.
 * Hotel as a base for Brotherhood of Steel
 * The White House utility tunnel
 * Scaffolding on 17th and Pennsylvania: there is a dead merc (possibly Talon Company, but he's not wearing Talon Co. armor), on the side with bent light pole, with a note (Pennsylvania Ave Explosives Note) about planted mines and activation switch location. The switch is past the dead merc. When you activate the switch, all the explosives go off in a chain reaction in the street.
 * In the Pulowski Preservation Shelter near the Penn. Ave/Seward Sq. Metro exit is a dead Protectron and an locked (very easy) Ammunition Box with Energy Cell ammunition

Notable loot

 * Chinese Army: Special Ops Training Manual in the Hotel on a small table near the HAM radio. (Has to be stolen.)
 * Tumblers Today in the Sewer (metro) by the ammo stash (hidden in a broken out wall in south east dead-end tunnel).
