Whether you say yes or no to the power of the Ouija board, there's no dismissing the legacy of this supposed spirit communication tool that inspires intrigue and amusement -- and sometimes fear. For more than 125 years, the Ouija has been an all-American invention that's alternately viewed as a practical way to reach out to the beyond, a slumber party game and a great narrative device in pop culture. Some even see it as a negative creation and a potential gateway for the nastier denizens of the spirit realm to enter our turf. Regardless of the Ouija's power (or lack thereof?), it is an undeniable part of our nation's history. That history was honored on Oct. 14 when the Talking Board Historical Society -- led by the world's leading talking board expert, Robert Murch -- worked with the City of Baltimore to install a plaque commemorating the location of an April 1890 séance where the board was named.
