A 2D (two-dimensional) barcode is a graphical image that stores information both horizontally -- as one-dimensional bar codes do -- and vertically. As a result of that construction, 2D codes can store up to 7,089 characters, significantly greater storage than is possible with the 20-character capacity of a unidimensional barcode.
One of the main reasons people think Centralia Pennsylvania is haunted is because of the 2006 horror film, Silent Hill. While the movieâs fictional events take place in West Virginia, elements of it seem to directly reference Centralia. These include cracked roads, steam rising from the ground, and dead vegetation.
Centralia PA has more people buried there than it has living residents. That fact alone is unsettling. As one drives around the town, three cemeteries can be found: Saint Ignatius, Saints Peter and Paul Orthodox, and Assumption of the Blessed Virgin Mary.
