Presque Isle Light

I have only been here during the day. So I have not seen or heard anything. It wasn't until I found it on the web that I knew it's history:
Another haunted spot is the Presque Isle Light near Alpena, Michigan. The tale is told here of a lighthouse keeper's wife who went insane because of the loneliness of her husband's position. It is said that he imprisoned the madwoman in a cell below the lighthouse, and she spent her last days there, shrieking insanely.It is said that her screams can still be heard today.
