Every Haunted Place in Ohio

Whenever anyone uses 'every' in a title I have my doubts. This one says it has 'every' haunted place in Ohio yet I know of some relatively nearby that are not included. The author also includes the Cincinnati subway but I don't know of any actual hauntings there.

Things that are noted include spirit drumming, orbs, a sea monster, an ouija board (which never results in anything good and trustworthy happening), Native American ghosts, a screaming bridge and a bunch of others.

There are also two town names which are really funny. One is Knockemstiff and the other is Mutton-jerk.
