Ghosts of Gettysburg: Walking on Hallowed Ground is a keep-you-up-all-night book from real life master ghost hunters, Drs. Dave and Sharon Oester, cofounders of the International Ghost Hunters Society, the largest ghost research society on the Internet. Drs. Dave and Sharon Oester spend their time traveling the back roads of America, investigating some of its most haunted places. Over a six-year period, they explored and recorded the amazing ghostly experiences of visitors to the Gettysburg battlefield. One year they devoted a full month for battlefield investigations and drove over 1,000 miles on the battlefield gathering data for this book. Drs. Dave and Sharon Oester were the first to hold ghost conferences in Gettysburg teaching about ghost photography and electronic voice phenomena known as EVP. Their annual ghost conferences started the ghost hunting movement in Gettysburg. Drs. Dave and Sharon Oester share 40 haunted sites on the battlefield, not according to folklore, but from their own personal investigations using scientific tools to validate the existence of ghosts. Each haunted site contains a short history of its part in this three-day battle. Read about the ten most haunted Civil War hospitals sites that can be visited by the reader.
