I read about it in a book called, "Weird Illinois". The guys who wrote it have a whole series for different states. I don't know how the other state books are, but the Illinois one is great.
That would be this book from Mark Sceurman & Mark Moranskip's Weird U.S. series.
The author of the Weird Illinois book, Troy Taylor, happens to be a personal friend of mine. Troy's website, Ghosts of the Prairie, is one that ghostlore and ghost hunting enthusiasts might enjoy; it contains many great stories.
A few months ago, I had the pleasure of a attending a presentation by Linda S. Godfrey, one of the authors of the Weird Wisconsin book in the same series. Had a chance to briefly chat with her afterwards; really nice, sweet lady. I purchased an autographed copy of the book from her that evening. She is also the author of another book in the series, Weird Michigan. I have yet to get a copy of this book, but am looking forward to ordering it soon.
Yes, the first book they wrote was weird New Jersey as the writers are native to NJ, a very interesting read.
