Gettysburg is known to be the most haunted place in the United States! If you are planning a trip there, be sure to check out the Ghosts of Gettysburg tour!
For years we went to Gettyburg on Halloween weekend. That was the good old days when you could go on the battlefied after dark, but thanks to vandals the park closes at dark.
We did this tour one year and found it to be alot of fun and definately puts you in the Halloween mood
