We were trapped by something evil that did not want to let us leaveâ€¦. The National Exchange:The national Exchange is one of the oldest and longest operating hotels on this side of the Mississippi. Built during the gold rush in the late 1800â€™s it was once regarded as the nicest place in an otherwise rough and dangerous town. This place was no stranger to violence and many people would lose their lives in fights, robberies, and accidents, some even taking their own lives. For years this building has been known to be the most haunted building in town, people have come from all over the world to see for themselves if these stories of ghosts and darkness are really true. Now its our turn and what we found, we were not quite ready for.
