Mason District

Mason District is an area in the Capital Wasteland located on the west side of Potomac in 2277. It is overrun by super mutants.

Layout
The Mason District mainly consists of a large flooded park surrounded by buildings, with a metro entrance in the south and north. Hubris Comics is at the northwest. In the flooded park, right outside Hubris Comics, are some super mutants with a captive.

Mason District can be reached through three underground tunnels:
 * Falls Church/Mason Dst Metro from Falls Church.
 * Through the flooded metro from the vicinity of Arlington Library. This is not recommended, unless you feel like fighting many mirelurks in an underground radioactive maze.
 * Taking the Hubris Comics utility tunnel from the vicinity of Wilhelm's Wharf near Grayditch and Super-Duper Mart.

Loot

 * Dean's Electronics, in the Pulowski Preservation shelter just outside Hubris Comics.
 * Guns and Bullets, at the sniper's nest on the second floor of a building that overlooks the park (southwest corner).

Appearances
Mason District appears only in Fallout 3.

Behind the scenes
Mason District is an actual location in nearby Fairfax County Virginia, and it even has a park complete with a playground.
