A distant relative of mine haunts your city, Barbara Fritchie. No clue how we are related, just remember hearing about it as a child. I also remember my grandmother telling me ghost stories about an old bridge. I can't remember what it was called, but there was a large Jug by it. I might have to look into that tour someday.
To the OP, I have taken both the walking tour of Gettysburg & the story time in the basement of the Farnsworth Inn. I enjoyed both of them.
