One of my favorite ghostly events is the annual Twilight Tours at West Baden where costumed interpreters portray pivotal characters from the hotel’s fabled past at the West Baden Springs Hotel. This year it's being held on September 24 & October 8 at 7:00 pm. Reservations required.
Here's a link to an article I wrote about it last year: http://www.nwitimes.com/lifestyles/travel/article_47a5dc16-07f0-5107-8676-28a830c395e7.html
