At the same time Thursday, other groups of ghost hunters trailed after costumed guides from other tour companies, passing each other, well, like apparitions in the night, in dark alleyways.

Such tours operate nightly from about March to November - likely numbering well over a thousand during the peak tourist season - creating crowds and controversy in the town.
The website HauntedAmericaTours.com, which urges people to "ghost-hunt responsibly," features "breaking paranormal news" and the latest information on tours in many cities: Philadelphia, Charleston, New Orleans, Chicago, among them.
Gettysburg, however, stands alone as the site of the bloodiest battle on U.S. soil, which left 7,000 dead over three days. There were piles of limbs in the streets, men dumped in shallow graves, and burning horses. Witnesses reported that the streets and creeks ran red.

The tragedy, combined with an estimated 200 Civil War buildings still standing, makes for great storytelling.
