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.
What has happened to Centralia over the past 50 years is quite humbling. However, visiting is a great way to better understand the destructive power of nature. While it might be one of Pennsylvaniaâs least likely and least publicized tourist attractions, visiting Centralia, PA is definitely worthwhile. Note: There are still residents that live in town, and to my knowledge, all of the remaining buildings are occupied.
