Mason District

 is an district on the west side of River Potomac. It is overrun by Super Mutants. This is where Hubris Comics is located.

Location
 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.
 * Easiest is probably to take the Hubris Comics Utility Tunnel from the vicinity of Wilhelm's Wharf near Grayditch and Super-Duper Mart.

Points of interest

 * The Hubris Comics building in the northwest contains many useful items.
 * In the flooded park outside Hubris Comics are some Super Mutants with a captive.

Notable loot

 * A Dean's Electronics in the Pulowski Preservation Shelter just outside Hubris Comics.
 * A Guns and Bullets on the second floor of a building that overlooks the park (SW corner). A sniper rifle and 3 ammunition boxes are also here in what appears to have been a sniper's nest.
 * 3 Chinese Assault Rifle and 4 ammo boxes just south of the captured wastelander.
