You would think the most haunted town in America would be something big, something shrouded in mystery. New Orleans comes to mind, hell even New York City could be super haunted! Well, it turns out the most haunted city is in Illinois. Yes, Alton Illinois to be exact. The city was built on limestone which is a guaranteed producer of paranormal activity. Something about limestone attracts all kinds of entities. I grew up in a house built on a limestone slab. That paired with 3 pre teen/teen age girls the poltergeist had a field day! Angsty energy is a favorite of some ghosts. Pay a visit to the most haunted town in America! Alton, Illinois.
